Abstract In the present paper, we investigate the influence of topological, noninertial and spin effects on the 2D Dirac oscillator in the presence of the Aharonov–Casher effect. Next, we determine the two-component Dirac spinor and the relativisti

In the present paper, we investigate the bound-state solutions of the noncommutative quantum Hall effect (NCQHE) with anomalous magnetic moment (AMM) in three different relativistic scenarios, namely: the Minkowski spacetime (inertial flat case), the

In this paper, we investigate the influence of the Aharonov-Casher (AC) effect on the relativistic and nonrelativistic energy spectra of a neutral Dirac particle with position-dependent mass (PDM). To exactly solve our system, we use the projection o

In this work, we study the (2 + 1)-dimensional Dirac equation for a neutral fermion with magnetic dipole moment in the presence of an electromagnetic field. Next, we explicitly determine the eigenfunctions and the relativistic energy spectrum of the

It is shown that the results of our paper are correct, although the use of the chirality operator $\gamma_5=\sigma_1$ in the paper is not correct, as fairly the authors of the Comment stated.

We obtain a static spherically symmetric wormhole solution due to the vacuum expectation value (VEV) of a Kalb-Ramond field. The Kalb-Ramond VEV is a background tensor field which produces a local Lorentz symmetry breaking (LSB) of spacetime. Conside

In this paper, we investigate the thermodynamic properties of a set of neutral Dirac particles in the presence of an electromagnetic field in contact with a heat bath for the relativistic and nonrelativistic cases. In order to perform the calculation

In this paper, we investigate the thermodynamic properties of an Aharonov-Bohm (AB) quantum ring in a heat bath for both relativistic and non-relativistic cases. For accomplishing this, we used the partition function which was obtained numerically us
