Thermodynamics of near BPS black holes in AdS4 and AdS7

Abstract

We develop the thermodynamics of black holes in AdS4 and AdS7 near their BPS limit. In each setting we study the two distinct deformations orthogonal to the BPS surface as well as their nontrivial interplay with each other and with BPS properties. Our results illuminate recent microscopic calculations of the BPS entropy. We show that these microscopic computations can be leveraged to also describe the near BPS regime, by generalizing the boundary conditions imposed on states.
