Conservative relativity principle: Logical ground and analysis of relevant experiments
(Springer Heidelberg, 2014) Yarman, Nuh Tolga; Yarman, Tolga; Missevitch, Oleg; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We 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.

Force law in material media and quantum phases
(Iop Publishing Ltd, 2016) Yarman, Nuh Tolga; Missevitch, Oleg; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We show that the known expressions for the force on a point-like dipole are incompatible with the relativistic transformation of force, and in this respect we apply the Lagrangian approach to the derivation of the correct equation for force on a small electric/magnetic dipole. The obtained expression for the generalized momentum of a moving dipole predicts two novel quantum effects with non-topological and non-dynamic phases, when an electric dipole is moving in an electric field, and when a magnetic dipole is moving in a magnetic field, respectively.

Lorentz transformation of a charge-current density and "relativistic polarization" of a moving current loop
(World Scientific Publ Co Pte Ltd, 2020) Yarman, Nuh Tolga; Missevitch, Oleg; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We show that the claim by Franklin (Int. J. Mod. Phys. A 35, 2050061 (2020)) with respect to the vanishing charge distribution over the perimeter of an electrically neutral moving current loop is erroneous and is based on a misinterpretation of physical meaning of Lorentz transformations. Moreover, we show that the development of nonvanishing electric dipole moment by a moving current loop (which we named as "relativistic polarization") represents a direct implication of covariant formulation of classical electrodynamics of material media. In this respect, we analyze some subtle effects related to the motion of magnetic dipoles in an electromagnetic field and disclose their physical meaning.

Mossbauer effect in rotating systems: possible explanation of the extra energy shift
(Springer Heidelberg, 2013) Yarman, Nuh Tolga; Yarman, Tolga; Missevitch, Oleg; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We 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.

New expressions for the Aharonov-Bohm phase and consequences for the fundamentals of quantum mechanics
(Walter de Gruyter Gmbh, 2024) Yarman, Nuh Tolga; Yarman, Tolga; Missevitch, Oleg; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We focus on new expressions for the Aharonov-Bohm (AB) phase proposed recently by C. Marletto and V. Vedral (Phys. Rev. Lett. 125, 040401 (2020)) and by our team (A. L. Kholmetskii et al., Ann. Phys., 434, 168627 (2021)). We emphasize the mismatch between the standard expression for the electric component of the AB phase and the expression by Marletto and Vedral for this component, which, as we show, has fundamental roots and indicates the need to use different expressions for the Hamiltonian of the radiative component and bound component of the electromagnetic (EM) field. We further show that the corrected expression for the AB phase of Marletto and Vedral and our expression for the AB phase do not coincide with its standard representation through the potentials of EM field (Y. Aharonov, D. Bohm, Phys. Rev. 115 (1959) 485) and contain additional terms, which straightforwardly allow to re-express the AB phase via electric and magnetic fields instead of scalar and vector potentials. The recognition of the field-dependent origin of the AB effect also requires to re-express the Hamiltonian of a charged particle through the EM field, which we show can be done in the only possible way. We discuss the physical meaning of the AB effect with the primary role of the EM field and also discuss some general quantum mechanical implications.

Poynting Theorem, Relativistic Transformation of Total Energy-Momentum and Electromagnetic Energy-Momentum Tensor
(Springer, 2016) Yarman, Nuh Tolga; Missevitch, Oleg; Yarman, Tolga; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We 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.

Thomas precession and Thomas-Wigner rotation: Correct solutions and their implications
(Iop Publishing Ltd, 2020) Yarman, Nuh Tolga; Missevitch, Oleg; Yarman, Tolga; Arik, Metin; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We address the Thomas precession for the hydrogen-like atom and point out that in the derivation of this effect in the semi-classical approach, two different successions of rotation-free Lorentz transformations between the laboratory frame K and the proper electron's frames, K-e(t) and K-e(t + dt), separated by the time interval dt, were used by different authors. We further show that the succession of Lorentz transformations K -> K-e(t) -> K-e(t + dt) leads to relativistically non-adequate results in the frame Ke(t) with respect to the rotational frequency of the electron spin, and thus an alternative succession of transformations K -> K-e(t), K -> K-e( t + dt) must be applied. From the physical viewpoint this means the validity of the introduced "tracking rule", when the rotation-free Lorentz transformation, being realized between the frame of observation K and the frame K(t) co-moving with a tracking object at the time moment t, remains in force at any future time moments, too. We apply this rule to the moving macroscopic objects and analyze its implications with respect to the Thomas-Wigner rotation and its application to astrometry. Copyright (C) EPLA, 2020.

Torque on an electric/magnetic dipole in the relativistic limit
(Springer Heidelberg, 2024) Kholmetskii, Alexander; Missevitch, Oleg; Yarman, Tolga
Using a covariant expression for the Lagrangian density of a polarized/magnetized material medium in an electromagnetic field (M. Fabrizio and A. Morri, Electromagnetism of Continuous Media (Oxford University Press, Oxford, 2003)), we derive for the first time in the classical framework the Lorentz-invariant expression for the torque exerted on an electric/magnetic dipole in the presence of electric and magnetic fields and discuss its implications. In particular, we show that in the strong relativistic limit, where the Lorentz factor associated with the moving dipole becomes much larger than unity, the torque terms with an explicit dependence on the velocity of dipole can remain comparable with the well-known terms p x E and m x B, where p, m are the electric and magnetic dipole moments, and E, B are the electric and magnetic fields, correspondingly.
