Motion of spinning particles around a polymer black hole in loop quantum gravity

K Chen, SW Wei - Physical Review D, 2024 - APS
In the curved spacetime background, the trajectory of a spinning test particle will deviate
from the geodesic. Using the effective potential method, we study the motion of a spinning …

[HTML][HTML] Cosmological constant from a deformation of the Wheeler–DeWitt equation

R Garattini, M Faizal - Nuclear Physics B, 2016 - Elsevier
In this paper, we consider the Wheeler–DeWitt equation modified by a deformation of the
second quantized canonical commutation relations. Such modified commutation relations …

[HTML][HTML] High temperature dimensional reduction in Snyder space

K Nozari, V Hosseinzadeh, MA Gorji - Physics Letters B, 2015 - Elsevier
In this paper, we formulate the statistical mechanics in Snyder space that supports the
existence of a minimal length scale. We obtain the corresponding invariant Liouville volume …

Natural cutoffs via compact symplectic manifolds

K Nozari, MA Gorji, V Hosseinzadeh… - Classical and Quantum …, 2015 - iopscience.iop.org
In the context of phenomenological models of quantum gravity, it is claimed that ultraviolet

Quantum mechanics on a curved Snyder space

S Mignemi, R Štrajn - Advances in High Energy Physics, 2016 - Wiley Online Library
We study the representations of the three‐dimensional Euclidean Snyder‐de Sitter algebra.
This algebra generates the symmetries of a model admitting two fundamental scales (Planck …

Viscous cosmologies

SB Medina, M Nowakowski… - Classical and Quantum …, 2019 - iopscience.iop.org
We probe into universes filled with quark gluon plasma with non-zero viscosities. In
particular, we study the evolution of a universe with non-zero shear viscosity motivated by …

[HTML][HTML] Polymeric quantization and black hole thermodynamics

MA Gorji, K Nozari, B Vakili - Physics Letters B, 2014 - Elsevier
Polymer quantization is a non-standard representation of the quantum mechanics that was

We provide a new approach to study the noncommutative effects on the neutral Dirac
particle with anomalous magnetic or electric dipole moment on the noncommutative plane …

[HTML][HTML] Quantum spacetimes from general relativity?

A Much - Journal of Geometry and Physics, 2025 - Elsevier
We introduce a non-commutative product for curved spacetimes, that can be regarded as a
generalization of the Rieffel (or Moyal-Weyl) product. This product employs the exponential …
