Geometric effects of torsion on black hole ringdown and shadows in Poincaré gauge gravity
Terkaa Victor Targema, Kazuharu Bamba, Riasat Ali +1
The paper studies how spacetime torsion in Poincaré gauge gravity modifies black hole ringdown signals and shadow images, focusing on Reissner‑Nordström‑like solutions where torsio…
On the Maldacena-Shenker-Stanford chaos bound in black hole spacetimes: Saturation, apparent violations, and their geometric origin
Terkaa Victor Targema, Kazuharu Bamba, Usman Zafar
Reported violations of the Maldacena-Shenker-Stanford (MSS) chaos bound in black hole spacetimes raise the question of whether they reflect a genuine breakdown, a feature of partic…
Thermodynamics and optical aspects of ModMax black holes in higher order curvature gravity with quintessence dark energy
Ahmad Al-Badawi, Usman Zafar, Abdul Jawad +1
In this work, we derive an exact black hole solution in higher-order curvature gravity by coupling an electromagnetic sector formulated within the ModMax framework to a quintessenc…
Generalized First Law and Smarr Formula: Beyond Additivity and Extensivity
Usman Zafar, Krishnakanta Bhattacharya, Kazuharu Bamba
The study of black hole thermodynamics becomes a central topic in gravitational physics, where the first law and the Smarr relation establish a deep connection between spacetime ge…
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…
Thermodynamic Topology and Photon Spheres Analysis of Black Holes in Brane-World: Insights from Barrow Entropy
Usman Zafar, Abdul Jawad, Kazuharu Bamba +4
We explore the thermodynamics and geothermodynamics of black holes with Barrow entropy in a brane-world scenario, where the horizon geometry of the black hole is regarded as a frac…
