Entropy and spectrum of near-extremal black holes: semiclassical brane solutions to non-perturbative problems

Abstract The black hole entropy has been observed to generically turn negative at exponentially low temperatures T ~ e − S 0 $$ T\sim {e}^{-{S}_0} $$ in the extremal Bekenstein-Hawking entropy S 0, a seeming pathology often attributed to missing non-perturbative effects. In fact, we show that this n...
