Dual Branes, Discrete Chain States and the Entropy of the Schwarzschild Black Hole
Abstract
Description
We review a recent proposal towards a microscopic understanding of the entropy of non-supersymmetric spacetimes -- with emphasis on the Schwarzschild black hole. The approach is based at an intermediate step on the description of the non-supersymmetric spacetime in terms of dual Euclidean brane pairs of type-II string-theory or M-theory. By counting specific chain structures on the brane-complex, it is shown that one can reproduce the exact Schwarzschild black hole entropy plus its logarithmic correction.
