Breaking of universal nature of central charge criticality in black holes in Gauss-Bonnet Gravity
Neeraj Kumar, Soham Sen, Sunandan Gangopadhyay
In this paper, we have studied the thermodynamics of Gauss-Bonnet black holes in D-dimensional spacetime. Here, the cosmological constant (), Newton's gravitational consta…
Signatures of quantum geometry from exponential corrections to the black hole entropy
Soham Sen, Ashis Saha, Sunandan Gangopadhyay
It has been recently shown in [Phys. Rev. Lett. 125 (2020) 041302] that microstate counting carried out for quantum states residing on the horizon of a black hole leads to a correc…
Path integral action for a resonant detector of gravitational waves in the generalized uncertainty principle framework
Soham Sen, Sukanta Bhattacharyya, Sunandan Gangopadhyay
The Heisenberg uncertainty principle gets modified by the introduction of an observer independent minimal length. In this work we have considered the resonant gravitational wave de…
Virtual transitions in an atom-mirror system in the presence of two scalar photons
Ashmita Das, Soham Sen, Sunandan Gangopadhyay
We examine the virtual transition of an atom-mirror system with the simultaneous emission of two scalar photons, where the atom and the mirror admit a relative acceleration between…
Phase transition structure and breaking of universal nature of central charge criticality in a Born-Infeld black hole
Neeraj Kumar, Soham Sen, Sunandan Gangopadhyay
In this paper we have considered the thermodynamics of a Born-Infeld black hole using inputs from the dual boundary field theory. Here, we have varied the cosmological consta…
Near horizon aspects (and beyond) of acceleration radiation of an atom falling into a large class of static spherically symmetric black hole geometries
Soham Sen, Rituparna Mandal, Sunandan Gangopadhyay
The near horizon aspects (and beyond) of a black hole metric, which belongs to a large class of static spherically symmetric black holes, are considered here. It has been realized…
