Black Hole Entropy production and Transport coefficients in Lovelock Gravity

26 Jun 2018 Fairoos C. Ghosh Avirup Sarkar Sudipta

We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of null Raychaudhuri equation. We show that the similarity between the expressions of entropy change of the black hole horizon due to perturbation and that of a fluid, which is out of equilibrium, transcends beyond general relativity to the Lovelock class of theories...
