Janus Black Holes

Dongsu Bak, Michael Gutperle, Romuald A. Janik

摘要:

本文考虑AdS 3中的Janus黑洞。这些是一个沿视界具有破缺平移对称性的爱因斯坦标量系统的静态解。这些解是有限温度下界面共形场论的对偶解。首先利用微扰理论构造了平面BTZ黑洞的近似解。数值和精确的解决方案有效的所有参数集,然后发现和比较。利用精确解对系统进行了热力学分析。计算了Janus黑洞的熵,发现黑洞的熵是未变形黑洞熵和与缺陷相关的纠缠熵之和.

英文摘要:

In this paper Janus black holes in AdS3 are considered. These are static solutions of an Einstein-scalar system with broken translation symmetry along the horizon. These solutions are dual to interface conformal field theories at finite temperature. An approximate solution is first constructed using perturbation theory around a planar BTZ black hole. Numerical and exact solutions valid for all sets of parameters are then found and compared. Using the exact solution the thermodynamics of the system is analyzed. The entropy associated with the Janus black hole is calculated and it is found that the entropy of the black Janus is the sum of the undeformed black hole entropy and the entanglement entropy associated with the defect.
