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…
