Thermodynamic analysis of charged anti-de Sitter black holes with cloud of strings in Einstein-bumblebee gravity via Bekenstein–Hawking and Tsallis entropies

Abstract We investigate the thermodynamic properties of charged anti-de Sitter (AdS) black holes surrounded by a cloud of strings in bumblebee gravity. In this framework, the cloud-of-strings parameter α and the Lorentz-violating parameter ℓ modify the horizon structure, the Hawk...

Geometric and wave optics analysis of BTZ-like charged wormholes with disclinations

We study the geometric and wave-optical properties of a charged BTZ wormhole (BTZCWH) spacetime carrying disclinations. The metric function \(f(r)=1-b_0/r-\mathcal {Q}^2 r^2/4\) has two positive zeros, an inner throat \(r_0\) and an outer zero \(r_*\) ; the static Lorentzian desc...
