Electric/magnetic dipolein an electromagnetic field: force, torque and energy
(Springer Verlag, 2014) Yarman, Nuh Tolga; Missevitch, O.; Yarman, T.; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
In this paper we collect the relativistic expressions for the force, torque and energy of a small electric/magnetic dipole in an electromagnetic field, which we recently obtained (A.L. Kholmetskii et al., Eur. J. Phys. 33, L7 (2011), Prog. Electromagn. Res. B 45, 83 (2012), Can. J. Phys. 9, 576 (2013)) and consider a number of subtle effects, characterized the behavior of the dipole in an external field, which seem interesting from the practical viewpoint. © 2014, Società Italiana di Fisica and Springer-Verlag Berlin Heidelberg.

Klein-Gordon equation for electrically charged particles with new energy-momentum operator
(Royal Soc, 2022) Yarman, Nuh Tolga; Yarman, T.; Missevitch, O.; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We address the Klein-Gordon equation for a spinless charged particle in the presence of an electromagnetic (EM) field, and focus on its known shortcoming, related to the existence of solutions with a negative probability density. We disclose a principal way to overcome this shortcoming, using our recent results obtained in the analysis of quantum phase effects for charges and dipoles, which prove the need to abandon the customary definition of the momentum operator for a charged particle in an EM field through its canonical momentum, and to adopt the more general definition of this operator through the sum of mechanical and EM momenta for the system 'charged particle in an EM field'. We show that the application of the new energy-momentum operator to the Klein-Gordon equation actually eliminates solutions with negative probability density. Some implications of the obtained results are discussed.

Quantum phase effects for electrically charged particles: converging descriptions via fields and potentials
(Springer Heidelberg, 2022) Yarman, Nuh Tolga; Missevitch, O.; Yarman, T.; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We analyze the physical meaning of quantum phase effects from a new perspective, related to our recent disclosure of two novel quantum phases for electric/magnetic dipoles - in addition to the previously known Aharonov-Casher and He-McKellar-Wilkens phases, and two novel quantum phases for point-like charged particles - in addition to the electric and magnetic Aharonov-Bohm phases. We show that the obtained complete expression for the quantum phase of a moving charge in an EM field allows to establish its direct link with the interactional electromagnetic momentum in the system "particle and external field" and to better understand the physical meaning of quantum phase effects, which is discussed using a number of particular examples.
