Quantum entropy of the Kerr black hole arising from gravitational perturbation
Jiliang Jing, Mu-Lin Yan
Abstract
The quantum entropy of the Kerr black hole arising from gravitational perturbation is investigated by using Null tetrad and t Hooftś brick-wall model. It is shown that effect of the gravitonś spins on the subleading correction is dependent of the square of the spins and the angular momentum per unit mass of the black hole, and contribution of the logarithmic term to the entropy will be positive, zero, and negative for different value of a/r+.
