JT gravity and deformed CFTs
Suchetan Das, Anirban Dinda
We propose alternative \textit{UV completion} of pure JT gravity as well as CFT coupled to JT gravity, via a class of \textit{deformed} 2D CFT. In AdS/CFT with a prescribed classic…
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…
The zeroth law of black hole thermodynamics in arbitrary higher derivative theories of gravity
Sayantani Bhattacharyya, Parthajit Biswas, Anirban Dinda +1
We consider diffeomorphism invariant theories of gravity with arbitrary higher derivative terms in the Lagrangian as corrections to the leading two derivative theory of Einstein's…
An entropy current and the second law in higher derivative theories of gravity
Sayantani Bhattacharyya, Prateksh Dhivakar, Anirban Dinda +3
We construct a proof of the second law of thermodynamics in an arbitrary diffeomorphism invariant theory of gravity working within the approximation of linearized dynamical fluctua…
An entropy current for dynamical black holes in four-derivative theories of gravity
Jyotirmoy Bhattacharya, Sayantani Bhattacharyya, Anirban Dinda +1
We propose an entropy current for dynamical black holes in a theory with arbitrary four derivative corrections to Einstein's gravity, linearized around a stationary black hole. The…
Fluid-gravity and membrane-gravity dualities - Comparison at subleading orders
Sayantani Bhattacharyya, Parthajit Biswas, Anirban Dinda +1
In this note we have compared two different perturbation techniques that could be used to generate solutions of Einstein's equations in presence of negative cosmological constant.…
The large D black hole dynamics in AdS/dS backgrounds
Sayantani Bhattacharyya, Parthajit Biswas, Bidisha Chakrabarty +2
We have constructed a class of perturbative dynamical black hole solutions in presence of cosmological constant. We have done our calculation in large number of dimensions. The inv…
