A Quantum-Gravity-Motivated GUP Effective Metric
M. H. Al Ghifari, M. F. Fauzi, A. Rohim +3
Recent critiques have addressed certain aspects of the generalized uncertainty principle (GUP) effective metric (Ong 2023). This study presents a scale-dependent quadratic GUP effe…
Renormalization group improved black holes in non-commutative momentum-dependent spacetime geometry
Gema Ilham Baskara Darman, Ar Rohim, Anto Sulaksono
We investigate black holes (BHs) in momentum-dependent spacetime geometry and assess its quantum Reissner-Nordström (RN) consistency with the weak gravity conjecture (WGC). Quantum…
Fermionic Casimir effect in the presence of compact dimension in field theory with Lorentz invariance violation
Ar Rohim, Apriadi Salim Adam
In this study, we investigate the effect of the Lorentz invariance violation on the Casimir energy and pressure of the massive fermion field in the presence of the compact dimensio…
Entanglement of the Vacuum between Left, Right, Future, and Past: Dirac spinor in Rindler spaces and Kasner spaces
Kazushige Ueda, Atsushi Higuchi, Kazuhiro Yamamoto +2
We study the relations of the positive frequency mode functions of Dirac field in 4-dimensional Minkowski spacetime covered with Rindler and Kasner coordinates, and describe the ex…
