A winding number analysis of Schwarzschild black hole stability in light of Planck-scale modified kinematics
Mohsen Khodadi, Nosratolla Jafari, Shahin Mamedov
Determining whether Planck-scale effects can stabilize black holes addresses fundamental questions about black hole evaporation and quantum gravity consistency. Here, we analyze th…
Black-hole thermodynamics in doubly special relativity: near-horizon g/f temperature scaling under a shared operational scale
Abdelmalek Boumali, Nosratollah Jafari
Doubly Special Relativity (DSR) deforms special-relativistic kinematics by introducing an invariant Planck energy scale alongside the speed of light, while preser…
Three-Dimensional Modified Dirac Oscillator in Standard and Generalized Doubly Special Relativity
Abdelmalek Boumali, Nosratollah Jafari
% Doubly Special Relativity (DSR) introduces, besides the invariant speed of light , an observer-independent high-energy % scale that deforms relativistic kinematics and can be…
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…
Klein--Gordon oscillator with linear--fractional deformed Casimirs in doubly special relativity
Abdelmalek Boumali, Nosratollah Jafari
We study the Klein--Gordon (KG) oscillator in a doubly special relativity (DSR) framework, where the mass-shell condition is deformed through a linear--fractional (Möbius-type) mo…
The Deformed Dirac Oscillator in Linear-Fractional Doubly Special Relativity
N. Jafari, A. Boumali
We study the -dimensional Dirac oscillator within a class of doubly special relativity (DSR) models generated by linear-fractional (projective) transformations on momentum s…
