Kerr-Newman黑洞熵与软毛

Kerr-Newman Black Hole Entropy and Soft Hair

Sasha Haco, Malcolm J. Perry, Andrew Strominger

摘要:

最近发现了一组非平凡地作用在Kerr视界上并形成一对左右维拉索罗代数的双同态。利用中心荷的边界公式,并假设Cardy公式适用于假定的对偶CFT,再现了Kerr黑洞的Bekenstein-Hawking熵.在本文中,额外的电荷的黑洞表明,需要一个最小的修改,然后再现的克尔-纽曼黑洞的贝肯斯坦-霍金熵的这种结构。

英文摘要:

Recently a set of diffeomorphisms were found which act nontrivially on the Kerr horizon and form a left-right pair of Virasoro algebras. Using the boundary formula for the associated central charge and assuming applicability of the Cardy formula to a putative dual CFT, the Bekenstein-Hawking entropy for the Kerr black hole was reproduced. In this paper, the addition of charge to the black hole is shown to require a minimal modification to this construction which then reproduces the Bekenstein-Hawking entropy for the Kerr-Newman black hole.
