Moduli-dependent one-loop entropy of hyperbolic BPS black hole in AdS
Imtak Jeon, Alokananda Kar, Binata Panda +1
We study one-loop logarithmic corrections to the entropy of static hyperbolic BPS black holes in asymptotically AdS spacetime. Our analysis is carried out in a consistent real-…

Zeroth law of black hole thermodynamics for higher derivative Proca theories
Parthajit Biswas, Alokananda Kar, Anowar Shaikh
We prove the constancy of surface gravity across a Killing horizon (not necessarily of bifurcate type) in arbitrary higher curvature theories of gravity coupled to Proca fields …

Iyer-Wald ambiguities and gauge covariance of Entropy current in Higher derivative theories of gravity
Alokananda Kar, Prateksh Dhivakar, Shuvayu Roy +2
In [arXiv:2105.06455, arXiv:2206.04538], the authors have been able to argue for an ultra-local version of the second law of black hole mechanics, for arbitrary diffeomorphism inva…
