Abstract

We review the design of alkali-metal-based half-Heusler alloys in the C1b structure using first-principles calculations for the purpose of searching spintronic materials. The structure has three phases, alpha (α), beta (β) and gamma (γ) phases. Each phase is characterized by the arrangements of three elements: an alkali-metal element, a 3d transition metal element and a group-VI, non-metal element in a primitive face-centered-cubic unit cell. Among the three phases, theβ-phase has the lowest total energy. The design principles of these alkali-metal-based half-Heusler alloys are guided by three requirements: (a) the nearest-neighbor configurations of the non-metal atom with the 3d transition metal element should be under the tetrahedral environment – to exhibit half metallic properties; (b) the electro-negativity of the non-metal atoms should be strong; and (c) the Pauli principle should be considered to align spins – to achieve the maximum magnetic moment. Using a prototype alloy, we demonstrate that these alloys: (i) are stable compared to half metals with the zinc-blende structure and (ii) have negligible spin-orbit effect which causes spin flip transitions to destroy the half metallicity. We predict two β-phase alloys :(α) exhibiting half-metallicity at their respective optimized lattice constants and at the absolute zero temperature and (β) having the largest possible magnetic moment for the 3d transition metal elements. They are potential candidates for spintronic applications. Work was supported by the US National Science Foundation.

Abstract

The first part of the report is devoted to the analysis of the possibility of the occurrence of nuclear processes at low energies (LENR). It is shown that even if the issue of overcoming the Coulomb barrier is left behind brackets, LENR cannot be exclusively nuclear fusion reactions, since in the synthesis the mass defect of the nuclei is so significant that it must inevitably lead to significant neutron or γ-activity. However, such a conclusion contradicts reliably established experimental facts, which state that during the course of LENR, no significant neutron or γ activity is recorded, and all daughter nuclei are stable (i.e., they are formed in the ground state). For the same reason, the physical mechanism of LENR cannot be the nuclear fission reaction. Since the maximum specific binding energy of the nuclei lies in the Fe region, the only possibility of the LENR behavior, which would not contradict the results of numerous experiments, is the existence of a hypothetical collective nuclear mechanism for the transformation of nuclei, in which the fusion and fission reactions proceed simultaneously, both to the right and to the left of Fe.It is obvious that within the framework of today's physical notions, the existence of such a physical mechanism for LENR behavior (transformation) seems impossible. It is well known that the average binding energy according to the periodic table is ~8 MeV/nucleon. Therefore, even if we allow the theoretical possibility of collective nuclear reactions (according to a completely new breakthrough physical mechanism) and demand compliance with all conservation laws, then there is absolutely no obvious answer to the question: is it possible to select combinations of stable isotopes of atoms in such a way that the difference between the total mass of maternal and daughter atoms differ by an energy of ~10 KeV, i.e. by the amount of electron shell binding energy? To answer this question, a phenomenological numerical model was developed. This model does not contain any assumptions about the physical mechanism of transformation, but relies only on conservation laws: energy, baryon, leptonic and electric charges. The problem facing the phenomenological model is the search for unknown sets of daughter nuclei that are close in mass (energy) to the original set of nuclei. Such a general approach to the problem was fruitful only for one reason: the number of stable isotopes in the periodic table is finite.The development of the model required a refinement of the criterion for the stability of atoms with respect to β^∓-decay and k-capture in isobaric series. The paper shows that the necessary and sufficient condition for the β^--stability of the nucleus of a neutral atom is the minimum mass of an atom in the isobar series, which does not always coincide with the minimum mass of the nucleus, often found in the literature. The development of the numerical algorithm of the phenomenological model required the replacement of the generally accepted concept of the binding energy of the atom (Eat.bond) by a new energy norm‖{X_i } ‖, which automatically takes into account the conservation of electric and baryon charges in nuclear transformations and vanishes on a set consisting of neutral hydrogen atoms. A criterion for the fruitfulness of the numerical phenomenological model was the results of experiments on high-current electric explosion of titanium (Ti) foils in water. From the results of mass spectrometric measurements of the foil residues, it follows that at the time of the electric explosion, a natural depletion of the natural mixture of Ti isotopes takes place due to the "disappearance" of 48Ti atoms. The "disappearance" of 48Ti atoms was accompanied by the appearance of a number of stable chemical elements: from the lightest ones to zinc (Zn). Since in addition to Ti atoms, the H and O atoms must inevitably get into the plasma channel, the process appeared as if the mother atoms "decay" into a whole spectrum of daughter chemical elements. Before the phenomenological model, the question was posed: if an ensemble of parent atoms participating in the nuclear transformation reaction is known (for example: isotopes 48Ti, 16O and 1H), can the ensemble of daughter atoms, qualitatively consistent with the results of the experiment, be obtained using a computer program? Computer simulation showed that without the nuclear processes going with the participation of weak nuclear interactions (β∓-decay and k-capture), i.e. transition of a neutron into a proton and vice versa, it is impossible to choose combinations that satisfy the above listed requirements. From the parent atoms, combinations in which the daughter atoms would be obtained with a number higher than that of Zn, cannot be obtained, which qualitatively agrees with the experimental data. From numerical calculations carried out within the framework of the phenomenological model it is follows: if the vanadium atoms (51V) were added to the mother atoms, then the 57Fe isotope should be formed. Moreover, this conclusion was independent from the calculation parameters: the quantitative ratio of iron isotopes was changed, but always the 57Fe isotope appears significantly more than in the equilibrium natural ratio of iron isotopes. 57Fe is a rare isotope and it is easy to identify. To verify the calculations, experiments were carried out, the results of which coincided with the prediction of the model. Thus, the paper shows that the existence of a hypothetical collective mechanism of low-energy transformation of atomic nuclei does not contradict the well-known fundamental conservation laws. Then we turn to a potential breakthrough theoretical explanation of this collective mechanism. From the observation of the “strange radiation” we obtain, we find some resemblance with the multi-soliton surfaces which are obtained as the partial embedding of the Lobachevski plane into the 3D Euclidean space. Since such embedding is known as not possible, we get around the difficulty by considering a non-Archimedean space. It is then obvious that we can embed the Archimedean Lobachevski plane into the 3D non-Archimedean space (Which is no more Euclidean formally speaking even if parallels may still exist). This allows us to consider a local geometry, at very small scale, which has negative curvature on the one hand and therefore allows an infinite number of possibilities to pave space through symmetric pattern repetition. We keep on in this direction, suggesting taking as a basic foundational principle of physics, Curie’s theorem about symmetries. From a brand new approach of symmetries, we are able to explain collective mechanisms of low energy transformations. We can even prove that there is no lower limit (but zero) for such mechanisms to occur if the experimental conditions are favorable. Finally, we infer that the norm which was introduced above with a purely experimental point of view of physics might correspond to some geometrical or topological properties of surfaces in the 3D non-Archimedean space, such, for example, as the genus of surfaces.

Abstract

We study the uncertainty relation for three quantum systems in the N-dimensional space by using the virial theorem (VT). It is shown that this relation depends on the energy spectrum of the system as well as on the space dimension N. It is pointed out that the form of lower bound of the inequality, which is governed by the ground state, depends on the system and on the space dimension N. A comparison between our result for the lower bound and recent results, based on information-theoretic approach is pointed out. We examine and analyze these derived uncertainties for different angular momentum with a special attention is made for the large N- limit.

Abstract

A new investigation carried out, analyzes the behavior of bodies with accelerations, and proposes new keys to better understand the mechanics of the universe, and to have a more real scientific cosmology. Applying the Field Theory to the dynamic magnitudes circumscribed to a body, the research has achieved a new conception of the coupling of these magnitudes, and the behavior of solid rigid bodies subjected to multiple simultaneous non-coaxial rotations. The results of the investigation are coherent with Einstein's theories on rotation, and with Kepler's laws, but it allows justifying other characteristics of the behavior of the celestial bodies, not foreseen in the other two models, such as the Dynamic equilibrium of the universe, the plane celestial systems or the rings of Saturn. Our research proposes, on the other hand, a different celestial mechanics and complementary to classical mechanics, specifically for systems accelerated by rotations. These new concepts illuminate the Theory of Dynamic Interactions (TDI), a new dynamic model for non-insertial systems with axial symmetry, which is based on the principles of conservation of measurable quantities: the notion of quantity, total mass and total energy. This Theory deduces a general equation of motion for bodies endowed with angular momentum, when subjected to successive non-coaxial rotations.

Abstract

The grand unification theory, also called the theory of everything, is the attempt to use one mathematic formula to explain all the fundamental forces and matters discovered so far and to integrate quantum physics and general relativity together. Quantum physics has been proven to be the fundamental physics for all elementary particles and three fundamental forces, electromagnetic, weak and strong forces. General Relativity is the proven theory for gravity. Many ways are proposed to incorporate gravity and general relativity into quantum physics. String theory is a promising candidate for the grand unification theory. Law of creation is searched in many traditions, cultures, and disciplines. So far, the fundamental law of creation remains an unsolved problem in physics. In this work, we will propose a law of creation based on Tao wisdom. This law of creation states that everyone and everything is created through yin yang interactions. Yin and Yang are two basic constituents of everyone and everything. Yin and Yang are opposite, relative, co-created, inseparable, and co-dependent. We will show that space and time is a yin yang pair. The interaction of space and time creates our universe. We will show how to derive string theory, superstring theory, and M-theory, as well as dark energy, dark matter, elementary particles, fundamental forces, and large structures of the universe from this law of creation.

Abstract

According to the big bang theory, the dense matter,right before the big explosion, was occupying zero space and infinite mass. According to the theory of special relativity, the dense matter was travelling at the speed of light. Explosions usually are spherical in shape; meaning that debris from the bang must be found at speeds faster than light, at the speed of light as well as our universe at speed lower than light. What really happened at some point in time 13.7 billion years ago, two particles of equal momentum and energy escaped the speed of light constant reference frame in the direction of motion; one particle was ejected in the direction of motion while the other in the opposite direction. The forward direction particle obtains a speed larger than light while the reverse particle obtained a speed lower than light. According to explained reasons the forward particle is the electron while the reverse particle is the proton for both particles’ effort to recombine in an effort to return to their ground state, which is the speed of light; being unable to reach the speed of light because of their increased masses, they stop at distance which is defined as the atomic radius in the hydrogen atom. Their effort to recombine explains the electrostatic forces. Eventually, the electron stopped at some supersonic speed, while the proton came to full rest. The speed of the electron was calculated and found to be to be according to rest observer 9.9x10 6 m/sec. the speed of electron in stable hydrogen atom is 2.2x10 6 m/sec as calculated by Bohr. The difference between the two above speeds, it is believed to be kinetic energy converted into heat calculated at 1.57x10 6 degrees Kelvin. In general, 13.7 billion years ago, instead of the whole universe was created at once; overheated hydrogen atoms were formed on continuous bases explaining the heat and abundance of hydrogen on newly formed stars. The continuous motion of electrons in orbit is also explained.

Abstract

The particle is represented by the wave packet in nonlinear space-time continuum. Due of dispersion, the packet periodically appears and disappears in movement and the envelope of the process coincides with the wave function. It was considered that the partial differential equation of telegraph-type describes the motion of such wave packet in spherical coordinate space r,( θ,φ). Also the analytical solution u r,( θ,φ) of this equation was constructed and it was supposed that the integral over all space of |grad |u|2 |2was equal to the mass of the particle identified with the wave packet. As the solution u r,( θ,φ) depends on two parameters L,m being positive integer, it is possible to calculate our theoretical particle masses M Lm for different L,m .Thus, we have obtained the theoretical mass spectrum of elementary particles. In comparison with known experimental mass spectrum it shows that our calculated theoretical mass spectrum is sufficiently verisimilar. In this article we discuss the problems of standard SM- model, super symmetry and string theory, compare the possibility to predict in UQT and SM and show that Standard Model has left unsettled a lot of fundamental problems solved by UQT.

Abstract

Observation of strong magnetic field close to the superconductivity and super fluidity is a clear evidence for disorder to order transition, predicted by Confined Quantum Field Theory.In Confined Quantum Field Theory, electrons and other elementary particles are represented by bounded connected manifold. With the topology represented the type of particle and metric as function of its energy. Therefore the radius of confinement is function of the particles energy. Photons are sub manifolds of charged particles. Exchange of energy in Confined Quantum Field Theory is not point wise but via a connected manifold. Therefore conservation of energy is fully respected. If an electron is in a periodic potential and the radius of confinement of electron is a number of period. The force over the connected manifold integrated to zero. And the electron moves without resistance. Disturbing a pre-superconductive electron results in emission of a photon which is a sub manifold, if during the short time of separation of the two manifold the electron receive a de-acceleration the same photon absorbs by the electron and no energy exchange takes place.

Abstract

Quantum vacuum has often been hypothesized as a special quantum fluid owning superfluid features, a special BEC treated with the equations of quantum physics, as for instance the Gross-Pitaevskii. But super fluidity seems now not to be the most interesting possible aspect of quantum vacuum. Indeed, using here a classical equation of fluid dynamics combined with the Lorentz factor (a nonlinearly modified Stokes's law), the unexpected shear-thickening nature of the physical vacuum is demonstrated, as the new equation is able to solve with 100% accuracy known anomalies as the Pioneer anomaly, previously treated via thermal simulations, and the anomalous perihelia precession of planetary orbits, for which the current formula of general relativity is newly derived in a dilatant quantum vacuum. The modified Stokes's formula is therefore presented in all its accuracy and predictive power for different fields of modern physics and aerospace engineering. Eventually, the relativistic mass increase effect observed in synchrotrons is presented as the consequence of the existence of a dilatant vacuum (increase of detected inertia). The obvious objection concerning the impossibility of observing stable planetary orbits in a viscous, dilatant vacuum is as well answered by the same modified Stokes's formula which predicts orbital stability over billions of years. The presented work is not speculative, since it offers precise calculations which may be considered demonstrations of the existence of a dilatant quantum vacuum, opening a new research field.

Abstract

It is easily shown that inertial reference frames can exist at any speed including the speed of light (sonic speed). The inside of a constant speed reference frame enjoy all laws of physics at any constant speed. For an inertial reference frame near the speed of light, Lorentz transformations are used to define measurements as observed from rest: Δx^'=Δx√(1-v^2⁄c^2 ) (1) m^'=m⁄√(1-v^2⁄c^2 ) (2) Δt'=Δt⁄√(1-v^2⁄c^2 ) (3) The primed terms are values as measured from rest, while the unprimed terms are as measured from inside the travelling reference frame with a velocity v. Equation (1) states that as the speed of the travelling reference is very close to sonic speed, it is observed from rest to be a thin infinite plane with the contracted thickness is the direction of motion; it is shown that the sheet collapses to zero volume at the sonic speed. Equations (2) and (3) state that the mass and time inside the travelling reference frame as observed from rest are of extremely large values at speeds near sonic. The thin space sheet near sonic speed as predicted by equation (1) is similar to a flying flag with bends. At sonic speed, a rest observer finds the main body of the sheet shrunk to zero volume, while the bends appear as islands in space. According to equation (2), the mass inside the travelling bends appear to be near infinity concentrated in small area exerting very large gravitational field, while time dilates. The velocity u’ inside the bends as observed from rest isdefined as the observed distance in (1) divided by the observed time in (2) u^' =⁡〖〖lim〗_(Δt^'→∞) (Δx^')/(Δt^' )〗= 0 (4) The velocity in (4) is an indication that kinetic energy in space bends is zero, hence no molecular motion and therefore no light can be observed to emerge. The inside of the bends are dead without motionThe bends clearly exercise the characteristics of black holes. Assume two large extent inertial reference frames travelling away from each other (not necessarily linear motion) at sonic speed. The speed of either one can be taken as reference speed. Setting the speed of one frame as zero, the other frame is travelling at sonic speed. Let the set rest reference frame be large enough to enclose our entire universe.An observer on the sonic reference frame finds that he is at rest and the other reference frame is travelling away at sonic speed. He finds our universe to be a point in space with infinite mass. The infinite mass may reflect the actual mass of our universe. Similarly, an observer at rest finds also the travelling reference frame to be a point in space with infinite mass. The infinite mass may also indicate the existence of a universe in the sonic reference frame. Therefore, it can be stated that two dimensional universes exist side by side unable to detect each other. It can be concluded that black holes are the gates that connect the two dimensional universes.

Abstract

Traditionally, analysis of the states of a non-relativistic quantum particle influenced by various potentials entails solving 1D static Schrödinger equations. For a bound state particle one begins with a 1D potential well and progresses the analysis considering various potentials. Naturally, one anticipates a seamless transition to the 2D space addressing issues of the same sort; literature search proves otherwise. Meaning, less attention is paid to the 2D quantum problems. One departs from unanswered issues of the 2D space and makes a quantum leap into the 3D. In 3D space, in place of tackling the hollow box problem the trend is to analyzing the Coulombian singular potential of a binary system, i.e. hydrogen atom. In this work we present the issues of a 3D hollow box. Our work is a mixed blend of analytic and numeric calculations. Its analytic side encounters the famous mathematical functions, its numeric side flourishes from utilizing a Computer Algebra System (CAS), specifically Mathematic.

Abstract

Using groups U(1)xSU(2)xSU(3) and the Pauli principle the mathematics of quantum physics from the standard model produces two sets of time independent quantum states in the gauge potential. They are n(n+1) and n(n-1) where n is the principal quantum number; oscillations between these states result in a one to one mapping with the Roberts-Janet Nuclear Periodic Table by interpretation of positive n values for condensed matter and negative n values for plasma prior to fusion. Occupation by bosons leads to increased energy densities in which a range of outcomes is discussed. A model of string theory at the nuclear end of the table is suggested merging into quantum loop gravity at the condensed matter end of the table. This results in a 5-dimensional Roberts-Janet Table in which explanations account for the structural change in both transition elements and lanthanides/actinides. By retro diction an explanation is found for recurring 8,18,32 patterns within the table as well as a prediction of an earlier recurring 2 first suggested by Janet. Observations of metallic hydrogen on Jupiter would appear to confirm this. A further prediction for the final state of electrons in element 138 and other elements is also made.

Abstract

Surface-Enhanced Optical Processes, SERS, SEHRS and SEIRA are of great interest for physics, chemistry and biology since they allow strongly increase sensitivity of these spectroscopic methods and are caused by a fundamental physical mechanism. It is so-called strong quadruple light-molecule interaction, arising in surface electromagnetic fields, strongly varying in space near a rough metal surface. Just this interaction is responsible for the enhancement in SERS ~ , in SEIRA and in SEHRS and significantly higher. Moreover, this interaction is the base for implementation of Single Molecule Detection by SERS, when the enhancement can achieve the value . This interaction is responsible for appearance of forbidden lines in all these processes on molecules with sufficiently high symmetry. In SEIRA and SEHRS it is expressed in their belonging to the vibrations with a unit irreducible representation of the molecule symmetry group. In SERS these lines are those, caused by vibrations transforming as the dipole moment component , which is perpendicular to the metal surface. One of the main fundamental properties of this interaction is that it is forbidden in molecules with cubic and icosahedral symmetry groups due to the electro dynamical law . This forbiddance is named as the Electro dynamical forbiddance and was observed in fullerene . At present the theory of the above mentioned processes, based on this concept is created and explains the most of the observed phenomena, accompanying SERS, SEHRS and SEIRA.

Abstract

Surrounding Matter Theory (SMT) an alternative theory to dark matter is presented. It is based on a modification of Newton's law. This modification is done by multiplying a Newtonian Potential by a given factor, which is varying with local distribution of matter, at the location Where the gravitational force is exerted with this new equation the model emphasizes that a Gravitational force is roughly inversely proportional to mass density at the location where this Force is applied. After presentation of the model, its dynamic is quickly applied to cosmology and galaxy structure. Some possible caveats of the model are identified.But the simple Mechanism described above suggests the idea of a straightforward solution to the following issues: virial theorem mystery, the value of cosmological critical density, the fine tuning issue, and expansion acceleration. A de Sitter Universe is predicted. The predicted time since last scattering is 68 h-1 Gyr, with this value the heterogeneities of large scale structures and galaxy formation might be better explained. Simulations of the stars in a galaxy have been executed with SMT. They show interesting speed profiles, and the fact that ring galaxies seems to be generated by SMT dynamic itself, without the help of any particular external event. Those Studies give motivation for scientific comparisons with experimental data.

Abstract

Using groups U(1)xSU(2)xSU(3) and the Pauli principle the mathematics of quantum physics from the standard model produces two sets of time independent quantum states in the gauge potential. They are n(n+1) and n(n-1) where n is the principal quantum number; oscillations between these states result in a one to one mapping with the Roberts-Janet Nuclear Periodic Table by interpretation of positive n values for condensed matter and negative n values for plasma prior to fusion. Occupation by bosons leads to increased energy densities in which a range of outcomes is discussed. A model of string theory at the nuclear end of the table is suggested merging into quantum loop gravity at the condensed matter end of the table. This results in a 5-dimensional Roberts-Janet Table in which explanations account for the structural change in both transition elements and lanthanides/actinides. By retro diction an explanation is found for recurring 8,18,32 patterns within the table as well as a prediction of an earlier recurring 2 first suggested by Janet. Observations of metallic hydrogen on Jupiter would appear to confirm this. A further prediction for the final state of electrons in element 138 and other elements is also made.

Abstract

The work shows that Planck’s values of length lp, time tp, mass mp and energy Ep are related to the basics of the material world, and therefore are of considerable interest for research. They were obtained by M. Planck in 1900 on the basis of three fundamental physical constants: Planck’s circular constant , the gravitational constant G, and the velocity of light in vacuum c, and have the form of quadratic dependencies , which allows to vary their sign (+) or (-) in the parity of these functions. In this case, their interpretation as time and anti-time, length and anti-length, mass and anti-mass, energy and anti-energy may be ambiguous, which makes it difficult to understand the physical nature and reality of these antipodes. This allows them to be given special properties and to build new cosmological theories on the basis of parity, including those of fantastic nature. The elucidation of these problems is an urgent task and has great theoretical and practical significance for the development of scientific ideas about the material world. It is shown in the paper that replacing Planck’s circular constant by Planck’s constant h allows one to obtain new values of Planck’s length, time and mass that are really related to the parameters of the material world. On this basis, within the framework of strict physical laws and regularities, Planck's oscillation was determined in the gravitational constant, which is a new fundamental physical constant – the oscillation νG of the gravitational field of the Universe, which is the basis of the entire material world? It was assigned to fundamental physical constants of the same level of significance as the gravitational constant G, Planck’s constant h and the velocity of light in vacuum c and is called Nastasenko’s quantum oscillation constant. Its application made it possible to refine the numerical values of the physical constants G, c, h, and most importantly to simplify and refine the physical regularities for determining Planck’s parameters of time, length and mass, eliminating the duality of their interpretation and the appearance of antipodes . The discovery of a new fundamental physical constant νG and the new principle of determining Planck’s values with obtaining new physical laws and regularities constitute the scientific novelty of the work performed. Its practical significance lies in deepening knowledge about the foundations of the material world and the Universe, which develops a general theory of knowledge. All tasks set in the work have been correctly solved and confirmed by reliable physical laws. The novelty, originality of the solution of the tasks set and the level of their validity make it possible to regard new physical laws and regularities as scientific discoveries.

Abstract

Quantum theory does not have a mechanism that explains how Nature implements probabilities. Thus, the main objective of this paper is to present new directions in understanding probabilities and randomness with the eventual objective of controlling photon localization. The expectation is to improve photon collection and loss mitigation. The paper analyses the differences between probabilities and randomness and proposes that (i) probability is a function of the particle structure and (ii) different and distinct from randomness; randomness originates from the localization material, and (iii) that all particles have internal clocks C; this internal clock is the mechanism for randomness. That is, the randomness of photon localization across the Point Spread Function is not due to the photon probability but due to the random behavior of electron shells receiving the photon localization. However, the shape of the intensity of localization is due to the shape of the photon’s probability function. Thus, a field theory for probabilities based on photon energy distribution and some experiments are proposed.

Abstract

A new approach for radiation reaction force is presented based on expressing the radiation reaction force in terms of the external force rather than the change of acceleration of the charge, and this approach is formulated for any arbitrary motion of the charged particle. In particular, the effect of radiation reaction on linear and circular acceleration, and a charge in and undulator device are presented using this approach. Experimental verification is required to see whether or not this approach leads us to the right direction to understand radiation reaction phenomenon.

Abstract

In recent years new interpretations of quantum atomic and nuclear physics were introduced in this research. The aim of the research is to develop a novel understanding of the atomic and nuclear structure in order to overcome problems in the quantum process perception. Two quantum aspects are to be addressed in the talk: a. The double-slit experiment demonstrating particle–wave duality:The particles pass through the two slits are no longer explained by terms of “particle splitting”. Instead the experiment is explained by collective connected identical Fermions demonstrating wave qualities during their motion as an attached group. b.Alpha particle tunneling emission from nucleus: The use of stationary Schrödinger equation in order to solve alpha particles emission from nuclei by Gamow was developed in the past in order to obtain the tunneling transmission coefficient, but the stationary assumption was not justified for this phenomenon. This analysis was carried out by dividing the problem into three ranges and solving the equations for each region. This new approach offers time-dependent quantum formalism for alpha particles emission. By looking at two parts: initial nucleus and after emission, the interpretation became in similarity to the gamma radiation emission. Phrasing alpha tunneling using a time-dependent formalism suggests a rational and a straightforward solution.

Abstract

The aim of our work is to show tunneling and transmission influence on the scattering theory basic concepts and quantities. To reach the goal we discuss the fundamental tunneling theory from monodromy point of view not applied yet in calculation even not used in academic courses. Monodromy is an alternate way to solve the Schrödinger equation. Instead of reversible and unitary equation systems describing in principle recoiled particles, there are applied two track matrix solutions connected with reflection and transmission scattering processes subordinate to multi-point boundary conditions. That new solutions generated by multiple matching 2x2 unimodular matrix wave-functions are irreversible. It means that scattering process from in state to our state is different from out to in. The linear operator which relates couple of the Schrödinger equation solutions before the inter-action area with another couple of solutions behind that interaction area is called the Schrödinger equation monodromy operator. These solutions describe the barrier reflection and transmission as the coupled equations. Usually it is possible to obtain tunneling time if the tunneling particle distance and speed are known. However the distance seeing by the particle can be different from that the external observer can see. This unsolved problem and how to find time from the wave function phase, rises at all calculation steps during scattering theory modification. We modify the scattering theory as follows: For the wave representing particle traveling through any layer system we calculate appropriate phase shifts comparing two methods. One is based on the standard scattering theory and is well known, another uses unimodular but not unitary M-monodromy matrix. Both methods are not equivalent due to different boundary conditions - in the one barrier case there exist analytical expressions showing difference. The standard scattering theory gives phase shifts denoted as l (practically it is phase shift increment ' l). Tunneling contribute to scattering and lead to modification of partial wave phase shifts due to interference of transmitted-tunneled wave with reflected one. In case of the single barrier (or potential well) it is analytically easy to show the difference. The reflected amplitude we denote R and transmitted one as T. The partial wave phase shift 2 0 is replaced by 0 = 2 0 + '0;RT. Assuming no tunneling (T = 0) in the limit we come back to classical theory with unitary evolution, the phase shifts l = 2 l + 'l;RT tend to ! 2 l according to standard scattering theory. On the other hand from comparison of one point and two point’s boundary condition, on the Monodromy base we modify the scattering theory to include tunneling. Then the optical theorem is also changed. The imaginary part of turned round the total forward scattering amplitude in R; T space is equal to the total cross section. The modification of the optical theorem is sketched using the partial wave method applied to the scattering - tunneling theory. 4π k P l (RlImfl −TlRefl) =R|f(Ω)|2 dΩ−P|Tl|2|fl|2 =R|f(Ω)|2 dΩ−R|fT(Ω)|2 dΩ In case of the pure reflection R = 1; T = 0 we recover the classical optical theorem, while for the pure transmission R = 0; T = 1 the total cross section is proportional to real part of the wave function which is responsible for transmission through potential field. Setting to zero the left hand side of the above equation we constitute the base of the generalized Ramsauer - Townsend effect. Any barrier system can be replaced by one generalized barrier with three solution regions U, B, f, each one described by the two track u1,i(kz),u2,i(kz);i ∈ (U,B,f) solutions. The input, barrier, output regions are denoted: input by in or U (- in case of radioactive decay) with the wave functions ΨU = Ψin ; barrier by B with the wave functions ΨB; and the output region by f with the wave functions Ψf. The domain of definition of the wave-functions can be divided into input, barrier and output regions. That division is schematically illustrated in eq.0.1 by the appropriate matrix composition. The multi-boundary conditions are incorporated in the structural matrix barrier in its elements α, ¯ β, ¯ γ, ¯ δ ¯. The structural barrier matrix represents the generalized barrier (which can be composed of any other barriers). The initial and final matrices correspond to input and output regions. Possible applications of the monodromy theory: • Explanation of Goos-Hänchen shift. • tunneling in three body system as well as in the optical model applied to coupled (reaction) channels etc. • Calculation of the optical, electromagnetic or particle dwell distances. • Two point boundary conditions enable us reanalysis of the Gamow theory within the optical model with tunneling through the barrier taken into consideration. In case of particle scattering by a nucleus or the spherical radioactive decay, the generalized barrier (if looking at the plane cross-section of the nucleus potential) consist of two potential barriers and the potential well w between them. In continuum between these barriers we can calculate the energy bands with high transmission probability for each l-partial wave. Between these bands there are regions where recoil probability increases. Concluding, projectile or the particle in the potential well with given energy can be reflected from the barrier or can be transmitted through it. The boundary conditions typical in all known codes (CRC-Coupled Reaction Channels, OMOptical Model, CC-Coupled Channels, i.e. all DWUCK’s, FRDWBA: LOLA.., CHUCK’s etc.) must be replaced by more general i.e. Dirichlet and von Neumann one.

Abstract

The context of this talk is Celestial Mechanics; more particularly, we study the symmetrical collinear four body problem where the bodies m3=m, m1=1, m2=1 and m4=m, m>0, are aligned in this order and move symmetrically about their center of mass. We derive the equations of motion, and the regularization of possible collisions is carried out. With the associated system of four ODE of first order, some general properties are given and the talk is mainly focused on orbits that eject from (and/or collide to) quadruple collision. In order to analyze the existence and the computation of such orbits, we consider the equilibrium points on the so called collision manifold. Such points are hyperbolic and their stable and unstable invariant manifolds provide the clue to compute ejection-collision orbits. The numerical methodology will be explained and some results presented. The tools applied in this problem are the usual ones in Dynamical Systems Theory.

Abstract

In this paper we present the bases of exact analytical aberration theory (EAAT) of centered optical systems containing conic surfaces. We develop exact functions for aberrations such as: paraxial chromatic aberration, on-axes spherical aberration, distortion, sagittal curvature, tangential curvature and field curvature. For meridional and sagittal coma we offer differential functions. All these functions allow to formulate theorems for existence, in above mentioned optical systems, of conjugate points and surfaces like: paraxial achromatic points, anastigmatic, plan sagittal, plan tangential, flat-field and orthoscopic surfaces and surfaces with corrected tangential or sagittal coma. For the correct elimination of aberrations in the design process of optical systems, we propose a new type of optical surfaces (so-called multi-conic surfaces). Each point of the multi-conic surface has strictly determined conic constant, different from the neighboring points. We show and analyze variety of examples with strictly corrected different aberrations (such as spherical aberration, distortion, astigmatism, sagittal curvature, tangential curvature etcetera). Using multi-conic surfaces we developed a simple method for designing of optical components and systems.

Abstract

We consider the CP (circularly polarized) problem, i.e., the Rydberg electron in a rotating electric field, whose dynamics is described by a Hamiltonian depending on one parameter, K > 0. We analyze the Hopf bifurcation appearing around one of the equilibrium points when K crosses a critical value Kcrit. The effect of this bifurcation, focusing on regular and bounded motion versus chaotic one is also discussed.

Abstract

Currently, the speed of light in vacuum c is determined most accurately (up to 9 characters). Plank’s constant h is determined up to 10 characters but within the measurement error its accuracy is 8 characters. The gravitational constant G is determined least accurately (up to 6 characters, 5 of which are accurate) in the Earth conditions the possibility of increasing the accuracy of its determining by experimental means has reached the technical limit. The complexity of the experiments for refining h also increases and requires great intellectual and material costs. Therefore, it is necessary to search for fundamentally new solutions. Based on the proposed of original method a system of rigorous computational dependencies is obtained. It follows from the fundamental physical constants c, h, G, and it allows us to obtain a new fundamental physical constant - the frequency of the gravitational field, which is expressed by exact quantum number ν G = 7.4∙10 42 s -1 (it is constant Nastasenko’s). It allows us to determine G up to 9 characters, which are 4 orders of magnitude more accurate than all its values found at the present time. It eliminates the need for the experimental defining of G, it is only sufficient to define the constants c and h, and increase of their accuracy will automatically lead to increase the accuracy of defining the value of G. In addition, based on the advanced and rigorous hypothesis on the numerical periodicity of the fundamental physical constants G, h, c, it is possible to refine them up to 12 characters, which can be confirmed experimentally.
