中微子的自旋对黑洞熵的影响

EFFECT OF SPIN ON THE BLACK HOLE ENTROPY DUE TO NEUTRINOS

用Newman Penrose形式和’tHooft砖墙模型 ,研究了中微子自旋对Schwarzschild anti deSitter黑洞量子熵的影响 .结果表明 ,-Λr3H>3m/ 2时 ,中微子自旋使黑洞量子熵增大 ;而 -Λr3H<3m/ 2时 。

By using the Newman-Penrose formalism and 't Hooft brick-wall model, the effect of spin on the quantum entropy of the Schwarzschild-anti-de Sitter black hole due to neutrinos is investigated. It is shown that when -Λr 3 H>3m/2, the spin of the neutrinos leads to a positive additional term in the quantum entropy of the black hole; but when -Λr 3 H<3m/2, the additional term is negative.
