具有整体对称性的AdS黑洞时空中的全息超导体

Songbai Chen, Liancheng Wang, Chikun Ding, Jiliang Jing

摘要:

我们研究了在具有整体对称性的Schwarzschild-AdS黑洞中通过带电复标量场的全息超导体。在对偶共形场论(CFTs)中计算了带电算符的凝聚,并讨论了整体场对凝聚形成的影响。此外,我们还用探针近似计算了电导,发现电导的性质与Schwarzschild-AdS黑洞中的电导性质非常相似。这些结果有助于我们进一步了解渐近AdS黑洞中的全息超导体。

英文摘要:

We study holographic superconductors in the Schwarzschild-AdS black hole with a global monopole through a charged complex scalar field. We calculate the condensates of the charged operators in the dual conformal field theories (CFTs) and discuss the effects of the global monopole on the condensation formation. Moreover, we compute the electric conductive using the probe approximation and find that the properties of the conductive are quite similar to those in the Schwarzschild-AdS black hole. These results can help us know more about holographic superconductors in the asymptotic AdS black holes.
