Positive-Energy Dirac Particles and Dark Matter

Universe
The relativistic positive-energy wave equation proposed by P. Dirac in 1971 is an old but largely forgotten subject. The purpose of this note is to speculate that particles described by this equation (called here Dirac particles) are natural candidates ...

On the 2D Dirac oscillator in the presence of vector and scalar potentials in the cosmic string spacetime in the context of spin and pseudospin symmetries

European Physical Journal C: Particles and Fields, 2019
The Dirac equation with both scalar and vector couplings describing the dynamics of a two-dimensional Dirac oscillator in the cosmic string spacetime is considered.

Greybody factors emitted by a regular black hole in a non-minimally coupled Einstein–Yang–Mills theory

European Physical Journal C: Particles and Fields, 2023
In this paper, we study the greybody factors (GFs) for fermions with different spins and bosons in the regular black hole (BH) predicted by a non-minimal Einstein–Yang–Mills (EYM) theory.

The 2D κ-Dirac oscillator

Physics Letters B, 2014
In this Letter, 2D Dirac oscillator in the quantum deformed framework generated by the κ-Poincaré–Hopf algebra is considered. The problem is formulated using the κ-deformed Dirac equation. The resulting theory reveals that the energies and wave functions

On the convergence rates of discrete solutions to the Wave Kinetic Equation

Mathematics in Engineering
In this paper, we consider the long-term behavior of some special solutions to the Wave Kinetic Equation. This equation provides a mesoscopic description of wave systems interacting nonlinearly via the cubic NLS equation.

Solution of Effective-Mass Dirac Equation with Scalar-Vector and Pseudoscalar Terms for Generalized Hulthén Potential

Advances in High Energy Physics, 2017
We find the exact bound state solutions and normalization constant for the Dirac equation with scalar-vector-pseudoscalar interaction terms for the generalized Hulthén potential in the case where we have a particular mass function m(x).

Phenomenology of the Magueijo-Smolin model of doubly special relativity using the non-relativistic limit of the Dirac equation, spin and Zeeman effect

Physics Letters B
In this article, we investigate the phenomenology of the Magueijo-Smolin (MS) model of Doubly Special Relativity by examining the non-relativistic (NR) limit of the Dirac equation and its implications for spin dynamics.
