摘要:

我们在弦云存在的 Einstein Gauss Bonnet 引力中获得了带电的渐近 AdS 黑洞解。结果表明,在化学势足够小的情况下,一定参数范围内存在三个黑洞;然而,当化学势较大时,这些黑洞合并为一个。黑洞的自由能是通过在壳欧几里得作用量中减去一个极端黑洞的贡献来计算的。我们研究了这些解的自由能和比热,结果表明中等尺寸的黑洞是不稳定的。作为应用,我们研究了对偶规范理论中的夸克-反夸克势。本研究为在凝聚态系统背景下研究对偶理论提供了必要的组成部分。

英文摘要:

We have obtained charged asymptotically AdS black hole solutions in Einstein Gauss Bonnet gravity in presence of string cloud. It turns out that there exist three black holes in certain range of parameters for small enough chemical potential. However, for large chemical potential, these black holes merge into a single one. The free energy of the black holes is computed from the on shell Euclidean action by subtracting the contribution of an extremal black hole. We have studied the free energy and specific heat of the solutions, which shows that the medium sized black hole is unstable. As an application, we have studied the quark-antiquark potential in the dual gauge theory. This study provides necessary ingredients for study of the dual theories in the context of condensed matter systems.
