Geometric effects of torsion on black hole ringdown and shadows in Poincaré gauge gravity
Terkaa Victor Targema, Kazuharu Bamba, Riasat Ali +1
Spacetime torsion provides a natural extension of general relativity and may lead to black hole solutions that differ significantly from their Einsteinian counterparts. We investig…

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…

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…
