Transitioning late-time cosmology with the Hubble parameterization
Vinod Kumar Bhardwaj, Saibal Ray, Kazuharu Bamba +1
We investigate a late-time cosmological model for a homogeneous and isotropic space-time in the Rastall theory. We explore the observational constraints on the Hubble parameter by…
Finslerian Wormholes in squared trace gravity
Z. Nekouee, B. R. Yashwanth, Manjunath Malligawad +3
We investigate traversable wormholes in squared-trace extended gravity within the framework of Finsler-Randers geometry equipped with the Barthel connection. The Einstein-Hilbert a…
Physical constraints on the Maldacena-Shenker-Stanford chaos-bound in black hole spacetimes
Terkaa Victor Targema, Kazuharu Bamba, Riasat Ali +1
Chaotic motion near black holes has recently been examined through the lens of the Maldacena-Shenker-Stanford (MSS) chaos-bound, but reported violations remain contradictory. A sig…
Gauss-Bonnet entropy and thermal dynamics of RN-AdS black holes
M. Z. Bhatti, Kazuharu Bamba, I. Siddique +2
We explore the thermodynamics of a novel solution for the Reissner-Nordström-Anti-de Sitter (AdS) black hole, uniquely incorporating the Gauss-Bonnet term. Unlike previous studies…
Differential topology and micro-structure of black hole in Einstein-Euler-Heisenberg spacetimes with exponential entropy
Muhammad Yasir, Tong Lining, Kazuharu Bamba
Exact black holes in the Einstein Euler-Heisenberg theory are explored with an exponential entropy framework by using the topological current -mapping theory. The topology class…
An innovative black hole solution and thermodynamic properties in higher-order curvature gravity with a scalar field
G. G. L. Nashed, Usman Zafar, Kazuharu Bamba
A spherically symmetric black hole solution defined by the gravitational mass is explored in higher-order curvature gravity associated with a scalar field. It is demonstrated that…
