The entropy is renormalized to the standard Bekenstein-Hawking formula with a one-loop correction arising from the higher curvature terms of the gravitational action. For the scalar field, the renormalized Newton constant and two renormalized coupling constants in the toroidal black hole are the same as those in the Reissner-Nordstrom black hole except for other one.展开更多

This method is universal to every kind of black holes. By means of thin film model, the entropy density at every point of the event horizon is calculated first, then the total entropy is obtained through integration.展开更多
