A comparison of two constructions for dynamical corrections to Wald entropy
Sayantani Bhattacharyya, Parthajit Biswas, Nilay Kundu
In this work, we analyze the differences and similarities between two recent constructions, which are distinct in their methodologies for extending the Wald entropy of stationary b…
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 …
Moving Mirrors, OTOCs and Scrambling
Parthajit Biswas, Bobby Ezhuthachan, Arnab Kundu +1
We explore the physics of scrambling in the moving mirror models, in which a two-dimensional CFT is subjected to a time-dependent boundary condition. It is well-known that by choos…
A classical Bousso bound for higher derivative corrections to general relativity
Sayantani Bhattacharyya, Parthajit Biswas, Nilay Kundu
Focussing on theories for which the higher derivative terms are considered as small corrections in the Lagrangian to Einstein's two-derivative theory of general relativity (GR), we…
Moving Interfaces and two-dimensional Black Holes
Parthajit Biswas, Suchetan Das, Anirban Dinda
Conformal field theories can exchange energy through a boundary interface. Imposing conformal boundary conditions for static interfaces implies energy conservation at the interface…
Holographic entanglement entropy for relativistic hydrodynamic flows
Jyotirmoy Bhattacharya, Parthajit Biswas, A. Chandranathan +1
We study the behaviour of holographic entanglement entropy (HEE) in near equilibrium thermal states which are macroscopically described by conformal relativistic hydrodynamic flows…
