全息拓扑半金属中的黑洞内部

Black hole interiors in holographic topological semimetals

Ling-Long Gao, Yan Liu, Hong-Da Lyu

摘要:

研究了全息Weyl半金属和全息节线半金属中的黑洞内部。我们发现黑洞奇点是Kasner形式的。在低温下的拓扑非平凡相中,度规场的Kasner指数和从视界到奇点的时间几乎是常数,这可能反映了拓扑半金属的拓扑性质。我们还发现了每个全息半金属模型中视界内部的一些特定行为。

英文摘要:

We study the black hole interiors in holographic Weyl semimetals and holographic nodal line semimetals. We find that the black hole singularities are of Kasner form. In the topologically nontrivial phase at low temperature, both the Kasner exponents of the metric fields and the proper time from the horizon to the singularity are almost constant, likely reflecting the topological nature of the topological semimetals. We also find some specific behaviors inside the horizon in each holographic semimetal model.
