关于黑洞相变的Maxwell等面积定律的注记

A note on Maxwell's equal area law for black hole phase transition

Shan-Quan Lan, Jie-Xiong Mo, Wen-Biao Liu

摘要:

在$T-r$平面上讨论了带电AdS黑洞的状态方程.从相变的角度出发,分别绘制了$T-S$、$P-V$、$P-ν$图,并利用等面积定律分别求出了三种情况下的相变点(P,T)。成功地得到了带电AdS黑洞的P-T的解析相变点关系。通过比较这三个结果,我们发现等面积定律可能不能直接用于$P-ν$平面。根据$T-S$,$P-V$的结果,我们绘制了$P-T-Q$图,发现对于高电荷黑洞,相变需要很低的温度条件.

英文摘要:

The state equation of the charged AdS black hole is reviewed in the $T-r$ plane. Thinking of the phase transition, the $T-S$, $P-V$, $P-ν$ graphs are plotted and then the equal area law is used in the three cases to get the phase transition point (P,T). The analytical phase transition point relations for P-T of charged AdS black hole has been obtained successfully. By comparing the three results, we find that the equal area law possibly cannot be used directly for $P-ν$ plane. According to the $T-S$, $P-V$ results, we plot the $P-T-Q$ graph and find that for a highly charged black hole a very low temperature condition is required for the phase transition.
