Noncommutative Schwarzschild Black Hole and Area Law

High Energy Physics - Theory 2009-04-22 v2 General Relativity and Quantum Cosmology

Abstract

Using a graphical analysis, we show that for the horizon radius rh4.8θr_h\gtrsim 4.8\sqrt\theta, the standard semiclassical Bekenstein-Hawking area law for noncommutative Schwarzschild black hole exactly holds for all orders of θ\theta. We also give the corrections to the area law to get the exact nature of the Bekenstein-Hawking entropy when rh<4.8θr_h<4.8\sqrt\theta till the extremal point rh=3.0θr_h=3.0\sqrt{\theta}.
