Affine quantization of the dynamical Reissner--Nordström region
Morteza Bajand, Babak Vakili
We study the quantum dynamics of the dynamical region of the Reissner--Nordström geometry using a minisuperspace reduction and affine quantization, which is naturally suited for p…
Kinematical correlations via -Poincaré coproducts
Mohammad Ali Gorji, Babak Vakili
We study a kinematical consequence of the Hopf-algebraic momentum composition law in -Minkowski spacetime. The same curved momentum space can be described in different coordina…
Relativistic transformation of temperature revisited
Soroor Pouryazdan, Babak Vakili
The relativistic transformation of temperature has long remained controversial, with the classical laws of Planck-Einstein, Ott-Eddington-Moller and Landsberg yielding conflicting…
Chaos and epoch structure in the deformed Mixmaster universe
Babak Vakili
We study the dynamics of the Bianchi~IX (Mixmaster) universe under classical polymerization and generalized uncertainty principle (GUP) deformation of the Poisson brackets. Startin…
Quantum teleportation in expanding FRW universe
Babak Vakili
We investigate the process of quantum teleportation in an expanding universe modeled by Friedmann-Robertson-Walker spacetime, focusing on two cosmologically relevant scenarios: a p…
A two-mode model for black hole evaporation and information flow
Erfan Bayenat, Babak Vakili
We develop and analyze a two-oscillator model for black hole evaporation in which an effective geometric degree of freedom and a representative Hawking radiation mode are described…
