Non-Abelian Dirac oscillator in a uniform Yang--Mills background: spin--isospin mixing and singlet--triplet splitting
Abdelmalek Boumali
We investigate a planar Dirac oscillator coupled to a spatially uniform \(\utwo=\uone\times\su\) Yang--Mills background. The gauge configuration, adapted from the Dossa--Avossevou…
The Generalized Dirac Oscillator in Doubly Special Relativity: A Complexified Morse Interaction
Abdelmalek Boumali
We study the one-dimensional Generalized Dirac Oscillator (GDO) under Doubly Special Relativity (DSR) kinematics. The GDO extends the Dirac oscillator by replacing the linear non-m…
Three-Dimensional Modified Klein--Gordon Oscillator in Standard and Generalized Doubly Special Relativity
Abdelmalek Boumali, Nosratollah Jafari
Doubly Special Relativity (DSR) augments special relativity by introducing, alongside the invariant speed of light , a second observer-independent scale typically associated wit…
Analysis of Spin-1/2 Particle Scattering in a Spinning Cosmic String Spacetime with Torsion, Curvature, and a Coulomb Potential
Abdelmalek Boumali
This paper investigates the scattering states of spin-1/2 particles in the spacetime of a spinning cosmic string with spacelike disclination and dislocation, with and without a Cou…
Quantum Dynamics of Scalar Particles in a Spinning Cosmic String Background with Topological Defects: A Feshbach-Villars Formalism Perspective
Sarra Garah, Abdelmalek Boumali
We study the relativistic quantum dynamics of spin-0 particles in the spacetime of a spinning cosmic string that carries both spacelike disclination (conical deficit ) and screw…
