Entropy from the foam
arXiv:hep-th/9906074 · doi:10.1016/S0370-2693(99)00700-5
Abstract
A simple model of spacetime foam, made by N wormholes in a semiclassical approximation, is taken under examination. We show that the Bekenstein-Hawking entropy is here ``quantized'' in agreement with the heuristic calculation of Bekenstein.
