从热力学相变看AdS黑洞的微观结构

Insight into the Microscopic Structure of an AdS Black Hole from Thermodynamical Phase Transition

Shao-Wen Wei, Yu-Xiao Liu

摘要:

与一般的热力学系统相比,我们完全从热力学的角度研究了带电反德西特黑洞可能的微观结构。引入黑洞分子的数密度来度量黑洞的微观自由度。我们发现,当黑洞系统越过小-大黑洞共存曲线时,数密度发生突变并伴随着潜热,而当系统通过临界点时,由于数密度的连续变化,系统发生了潜热消失的二级相变.此外,热力学标量曲率表明两个黑洞分子之间存在弱吸引相互作用。这些现象可能为带电反德西特黑洞的微观结构提供新的见解。

英文摘要:

Comparing with an ordinary thermodynamic system, we investigate the possible microscopic structure of a charged anti-de Sitter black hole completely from the thermodynamic viewpoint. The number density of the black hole molecules is introduced to measure the microscopic degrees of freedom of the black hole. We found that the number density suffers a sudden change accompanied by a latent heat when the black hole system crosses the small-large black hole coexistence curve, while when the system passes the critical point, it encounters a second-order phase transition with a vanishing latent heat due to the continuous change of the number density. Moreover, the thermodynamic scalar curvature suggests that there is a weak attractive interaction between two black hole molecules. These phenomena might cast new insight into the underlying microscopic structure of a charged anti-de Sitter black hole.
