The Entropy of Higher Dimensional Nonrotating Isolated Horizons from Loop Quantum Gravity

preprint2014arXivOpen access

Abstract

In this paper, we extend the calculation of the entropy of the nonrotating isolated horizons in 4 dimensional spacetime to that in a higher dimensional spacetime. We show that the boundary degrees of freedom on an isolated horizon can be described effectively by a punctured SO(1,1)SO(1,1) BF theory. Then the entropy of the nonrotating isolated horizon can be calculated out by counting the microstates. It satisfies the Bekenstein-Hawking law.
