Non-extensive entropy signatures in compact star
B. N. Jayawiguna, M. H. Al Ghifari, A. Rohim +1
The non-extensive entropy models applied to the black-hole horizon are connected to the generalized Einstein--Hilbert action, , via the Wald entropy formalism. We demonstrate…
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…
Thermal Casimir Effect in A Schwarzschild-like Wormhole Spacetime
Arista Romadani, Apriadi Salim Adam, Ar Rohim +2
We study the finite-temperature Casimir effect for a massless scalar field confined between two parallel plates in a Schwarzschild-like wormhole spacetime. Imposing Dirichlet bound…
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…
Violation of the two-time Leggett-Garg inequalities for a harmonic oscillator
Kosei Hatakeyama, Daisuke Miki, Masaki Tani +5
We investigate the violation of the Leggett-Garg inequalities for a harmonic oscillator in various quantum states. We focus on the two-time quasi-probability distribution function…
Casimir effect of Lorentz-violating charged Dirac in background magnetic field
Ar Rohim, Apriadi Salim Adam, Arista Romadani
We study the effect of the Lorentz symmetry breaking on the Casimir energy of charged Dirac in the presence of a uniform magnetic field. We use the boundary condition from the MIT…
Massive fermion between two parallel chiral plates
Ar Rohim, Apriadi Salim Adam, Kazuhiro Yamamoto
We study the system of a massive fermion field confined between two parallel plates, where the properties of both plates are discussed under chiral MIT boundary conditions. We inve…
Effects of chiral MIT boundary conditions for a Dirac particle in a box
Ar Rohim, Kazuhiro Yamamoto
We investigate the effects of the chiral MIT boundary conditions for a Dirac particle in a 1D box. We show how the boundary condition affects the discrete momentum, energy level, t…
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…
Relativistic quantum bouncing particles in a homogeneous gravitational field
Ar Rohim, Kazushige Ueda, Kazuhiro Yamamoto +1
In this paper, we study the relativistic effect on the wave functions for a bouncing particle in a gravitational field. Motivated by the equivalence principle, we investigate the K…
