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.…
