RG Flow and Thermodynamics of Causal Horizons in Higher-Derivative AdS Gravity
Shamik Banerjee, Arpan Bhattacharyya
In arXiv:1508.01343 [hep-th], one of the authors proposed that in AdS/CFT the gravity dual of the boundary -theorem is the second law of thermodynamics satisfied by causal horiz…
Entropy functionals and c-theorems from the second law
Srijit Bhattacharjee, Arpan Bhattacharyya, Sudipta Sarkar +1
We show that for a general four derivative theory of gravity, only the holographic entanglement entropy functionals obey the second law at linearized order in perturbations. We als…
Holographic Lifshitz fluids in 1+1 dimensions
Arpan Bhattacharyya, Dibakar Roychowdhury
In this paper, using the techniques of Gauge/gravity duality we explore the hydrodynamic regime of Lifshitz fixed points in dimensions. The speed of sound in the no…
Renormalized Entanglement Entropy for BPS Black Branes
Arpan Bhattacharyya, S. Shajidul Haque, Alvaro Veliz-Osorio
We compute the renormalized entanglement entropy (REE) for BPS black solutions in , 4d gauged supergravity. We find that this quantity decreases monotonically with the…
