Article Citation Count: 9Mossbauer effect in rotating systems: possible explanation of the extra energy shift(Springer Heidelberg, 2013) Kholmetskii, Alexander; Yarman, Tolga; Missevitch, Oleg; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringWe analyze the Mossbauer experiments in rotating systems, where an absorber orbits around a source of resonant radiation. As the recent measurements indicate, in this configuration the relative energy shift between emission and absorption lines emerges not only due to the dilation of time in the rotating absorber (the second-order Doppler effect), but it is also due to some effect of unknown nature, which contributes more than 20% to the value of the usual relativistic dilation of time. We suggest a physical explanation of such an extra energy shift, based on the Pure Bound Field Theory (PBFT), which we recently suggested (A. L. Kholmetskii et al., Eur. Phys. J. Plus 126, 33 (2011), 126, 35 (2011)). In particular, PBFT predicts the additional dilation of time for electrically bound particles, which, to the accuracy of calculations c(-2), is linearly added to the conventional relativistic time dilation effect. Applying this result to resonant nuclei in a crystal, we obtain a qualitative agreement between calculated and measured data of the extra energy shift between emission and absorption resonant lines for the Mossbauer effect in rotating systems. Some implications of the results obtained are discussed.Article Citation Count: 11Novel theory leads to the classical outcome for the precession of the perihelion of a planet due to gravity(Physics Essays Publication, 2014) Yarman, Tolga; Kholmetskii, Alexander; Arik, Metin; Yarman, Ozan; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringWe offer a novel method which lets us derive the same classical result for the precession of the perihelion of a planet due to the gravitational effects of the host star. The theoretical approach suggested earlier by the first author is erected upon just the energy conservation law, which consequently yields the weak equivalence principle. The precession outcome is exactly the same as that formulated by the general theory of relativity (GTR) for Mercurial orbit eccentricities, but the methodology used is totally different. In our approach, there is no need to make any categorical distinction between luminal and subluminal matter, since, as we have previously demonstrated, our theory of gravity is fully compatible with the foundations of quantum mechanics. Our approach can immediately be generalized to the many-body problem, which is otherwise practically impossible within the framework of GTR. Our approach thus leads to a unified description of the microworld and macroworld physics.

L.; Yarman, T.; Missevitch, O. V.; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringThe paper is motivated by our idea to re-define the momentum operator in quantum physics through the sum of mechanical and electromagnetic momenta for the system "charged particle in an electromagnetic field" instead of its canonical momentum, which occurred successful in describing quantum phase effects for charges and dipoles (Kholmetskii et al. in Ann. Phys. 392:49, 2018; Sci. Rep. 8:11,937, 2018). Furthermore, we show how a recently obtained expression for the "point-by-point" quantum phase of a charged particle in the framework of a fully quantized model of the Aharonov-Bohm effect (Marletto and Vedral in Phys. Rev. Lett. 125:040,401, 2020) supports the re-definition of the momentum operator in quantum mechanics from the theoretical side. These results motivated us to re-analyze the fundamental equations of relativistic quantum mechanics with a new energy-momentum operator. In this contribution, we solve the Dirac equation for an electrically bound electron with a new energy-momentum operator and extend the obtained solutions to the precise physics of simple atoms in the form of an effective theory, which does not touch the diagram technique of QED. We find that for majority of problems of precise physics of simple atoms, both definitions of the energy-momentum operator, yield indistinguishable results with modern measurement precision. An important exception is the spectroscopy of ortho-positronium, which occurs crucial in choosing the correct expression for the energy-momentum operator, and it shows that the available measurement data rather support the new definition of this operator.Article Citation Count: 1GENERALIZED LORENTZ GROUP OF SPACE-TIME TRANSFORMATIONS(Turkic World Mathematical Soc, 2020) Yarman, Tolga; Altintas, Azmi A.; Kholmetskii, Alexander L.; Arik, Metin; Marchal, Christian B.; Yarman, Ozan; Ozaydin, Fatih; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringWe examine how Lorentz Symmetry (LS) breaks down in Yarman-Arik-Kholmetskii (YARK) theory of gravitation through an entirely different mechanism than that under metric theories of gravity. Said mechanism can be right away extended to all other fields of interaction under Yarman's Approach that forms the basis of YARK theory. The result is the disclosure of a new "Generalized Lorentz Group" of space-time transformations which contains an additional parameter denoting the interactional energy per unit mass. Hence, the core finding herein is that the Minkowskian metric for an empty space-time should, when one is in the presence of gravity or any other force field, be replaced by general equalities involving a novel coupling parameter for either attraction or repulsion..Article Citation Count: 5Conservative relativity principle: Logical ground and analysis of relevant experiments(Springer Heidelberg, 2014) Kholmetskii, Alexander; Yarman, Tolga; Missevitch, Oleg; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringWe suggest a new relativity principle, which asserts the impossibility to distinguish the state of rest and the state of motion at the constant velocity of a system, if no work is done to the system in question during its motion. We suggest calling this new rule as "conservative relativity principle" (CRP). In the case of an empty space, CRP is reduced to the Einstein special relativity principle. We also show that CRP is compatible with the general relativity principle. One of important implications of CRP is the dependence of the proper time of a charged particle on the electric potential at its location. In the present paper we consider the relevant experimental facts gathered up to now, where the latter effect can be revealed. We show that in atomic physics the introduction of this effect furnishes a better convergence between theory and experiment than that provided by the standard approach. Finally, we reanalyze the Mossbauer experiments in rotating systems and show that the obtained recently puzzling deviation of the relative energy shift between emission and absorption lines from the relativistic prediction can be explained by the CRP.Article Citation Count: 9UNIFICATION OF SPACE-TIME-MATTER-ENERGY(Ministry Communications & High Technologies Republic Azerbaijan, 2008) Sobczyk, Garret; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringA complete description of space-time, matter and energy is given in Einstein's special theory of relativity. We derive explicit equations of motion for two falling bodies, based upon the principle that each body must subtract; the mass-equivalent for any change in its kinetic energy that is incurred during the fall. We find that there are no singularities and consequently no blackholes.Article Citation Count: 0Propagation Properties of Bound Electromagnetic Field: Classical and Quantum Viewpoints(Springer, 2020) Kholmetskii, A. L.; Missevitch, O. V.; Yarman, T.; Smirnov-Rueda, R.; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringThe present work is motivated by recent experiments aimed to measure the propagation velocity of bound electromagnetic (EM) field (Missevitch, et al. in EPL 93:64004, 2011; de Sangro et al. in Eur Phys J C 75:137, 2015) that reveal no retardation in the absence of EM radiation. We show how these findings can be incorporated into the mathematical structure of special relativity theory that allows us to reconsider some selected problems of classical and quantum electrodynamics. In particular, we come to the conclusion that the total four-momentum for a classical system "particles plus fields" ought to be a present state function of moving charges if EM radiation is negligible. In quantum domain, we analyze novel definition of the momentum operator recently suggested in the study of quantum phase effects (Kholmetskii et al. in Sci. Rep. 8:11937, 2018). It implies that bound EM field energy and momentum are to be present state functions, too. Being in agreement with reported experiments, these conclusions suggest the necessity to carry out more precise experimental verifications for additional and independent determination of propagation properties of bound EM fields. A scheme of a possible experiment on this subject is also proposed.Article Citation Count: 3Poynting Theorem, Relativistic Transformation of Total Energy-Momentum and Electromagnetic Energy-Momentum Tensor(Springer, 2016) Kholmetskii, Alexander; Missevitch, Oleg; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringWe address to the Poynting theorem for the bound (velocity-dependent) electromagnetic field, and demonstrate that the standard expressions for the electromagnetic energy flux and related field momentum, in general, come into the contradiction with the relativistic transformation of four-vector of total energy-momentum. We show that this inconsistency stems from the incorrect application of Poynting theorem to a system of discrete point-like charges, when the terms of self-interaction in the product (where the current density and bound electric field are generated by the same source charge) are exogenously omitted. Implementing a transformation of the Poynting theorem to the form, where the terms of self-interaction are eliminated via Maxwell equations and vector calculus in a mathematically rigorous way (Kholmetskii et al., Phys Scr 83:055406, 2011), we obtained a novel expression for field momentum, which is fully compatible with the Lorentz transformation for total energy-momentum. The results obtained are discussed along with the novel expression for the electromagnetic energy-momentum tensor.Article Citation Count: 0RETRACTION: Conservative relativity principle and energy-momentum conservation in a superimposed gravitational and electric field (Retraction of Vol 95, 10.1139/CJP-2017-0290, 2017)(Canadian Science Publishing, 2017) Kholmetskii, Alexander; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems Engineering[No Abstract Available]Article Citation Count: 4Systematization of α-decaying nuclei based on shell structures: The case of even-odd nuclei(Springer, 2017) Yarman, Tolga; Zaim, Nimet; Yarman, O.; Kholmetskii, Alexander; Arik, Metin; Enerji Sistemleri Mühendisliği / Energy Systems EngineeringPreviously, we provided a novel systematization of alpha-decaying even-even nuclei starting with the classically adopted mechanism (Yarman et al., Eur. Phys. J. A 52, 140 (2016)). The decay half-life of an alpha-decaying nucleus was framed so that i) the alpha-particle is taken at the outset to be born inside the parent nucleus with a given probability, ii) where it then keeps on bouncing off of the barrier of the parent nucleus till iii) it finally tunnels through the barrier. Knowing beforehand the measured decay half-life, we have taken into consideration, as a parameter, the probability of the alpha-particle being first born within the parent before it is emitted. We thence developed a scaffold based on shell properties of families composed of alike even-even nuclei. Nevertheless, our model allows us to incorporate any alpha-decaying nuclei, and along this line, we present a follow-up systematization of even-odd nuclei, with cases of odd-even and odd-odd alpha-decaying nuclei pending to be considered in a separate contribution. Notwithstanding, we make an effort herein to expand our approach to investigate the effect of "pairing" (e.g., when a number of nucleons in the given nucleus becomes an even number, instead of the initial odd number, due to the addition of at least one neutron). Our results show that "pairing", as expected, definitely increases the stability of the given nucleus.
