相变的统一图象:从液-汽系统到AdS黑洞

A unified picture of phase transition: from liquid-vapour systems to AdS black holes

Rabin Banerjee, Sujoy Kumar Modak, Dibakar Roychowdhury

摘要:

基于热力学的基本概念,我们研究定义在反德西特(AdS)空间中的黑洞的相变。这种方法与以前理解吉布斯势一阶导数不连续且满足Clausius-Clapeyron方程的液-汽相变的方法是一致的。这里的想法是考虑AdS黑洞作为巨正则系综和研究相变定义的吉布斯势的二阶导数的不连续性。我们分析检查,这个相变之间的“较小”和“较大”的质量黑洞遵守在临界点定义的Ehrfest关系,因此确认二阶相变。这包括爱因斯坦引力中的旋转和带电黑洞。

英文摘要:

Based on fundamental concepts of thermodynamics we examine phase transitions in black holes defined in Anti-de Sitter (AdS) spaces. The method is in line with that used a long ago to understand the liquid-vapour phase transition where the first order derivatives of Gibbs potential are discontinuous and Clausius-Clapeyron equation is satisfied. The idea here is to consider the AdS black holes as grand-canonical ensembles and study phase transition defined by the discontinuity of second order derivatives of Gibbs potential. We analytically check that this phase transition between the `smaller' and `larger' mass black holes obey Ehrenfest relations defined at the critical point and hence confirm a second order phase transition. This include both the rotating and charged black holes in Einstein gravity.
