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…

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…
