  • Generalized second law at linear order for actions that are functions of Lovelock densities 
    Sarkar, Sudipta; Wall, Aron C. (American Physical Society, 2013-08)
    In this article we consider the second law of black holes (and other causal horizons) in theories where the gravitational action is an arbitrary function of the Lovelock densities. We show that there exists an entropy which ...
  • Holographic entropy increases in quadratic curvature gravity 
    Bhattacharjee, Srijit; Sarkar, Sudipta; Wall, Aron C. (American Physical Society, 2015-09)
    Standard methods for calculating the black hole entropy beyond general relativity are ambiguous when the horizon is nonstationary. We fix these ambiguities in all quadratic curvature gravity theories, by demanding that the ...
