Microscopic Origin of the Bekenstein-Hawking Entropy

arXiv:hep-th/9601029 · doi:10.1016/0370-2693(96)00345-0

Abstract

The Bekenstein-Hawking area-entropy relation $S_{BH}=A/4$ is derived for a class of five-dimensional extremal black holes in string theory by counting the degeneracy of BPS soliton bound states.
