全相空间复杂热力学系统的Escherichfest格式

Ehrenfest scheme for complex thermodynamic systems in full phase space

Zixu Zhao, Jiliang Jing

摘要:

对于具有多对强/广变量的热力学系统,当系统的热力学系数在相边界上达到有限或无穷大时,我们得到了全相空间中的两类Escherichfest方程,并发现这两类方程的矩阵的秩可以告诉我们相边界的维数.我们也将这种处理应用到RN-AdS黑洞。

英文摘要:

For a thermodynamic system with multiple pairs of intensive/extensive variables and the thermodynamical coefficients attain finite or infinite values on the phase boundary, we obtain the two classes of Ehrenfest equations in the full phase space, and find that the rank of the matrix for these equations can tell us the dimensions of the phase boundary. We also apply this treatment to the RN-AdS black hole.
