几何热力学中的相变

Phase transitions in geometrothermodynamics

H. Quevedo, A. Sanchez, S. Taj, A. Vazquez

摘要:

利用几何热力学的形式主义,我们研究了不同热力学系统的平衡流形的几何性质。从相流形的勒让德不变度量出发,导出了在一阶和二阶相变点处曲率奇异的平衡流形的热力学度量.我们的结论是,热力学曲率的平衡流形,定义在geometrothermodynamics,可以被用来作为一种措施的热力学相互作用,在不同的系统与两个和三个热力学自由度。

英文摘要:

Using the formalism of geometrothermodynamics, we investigate the geometric properties of the equilibrium manifold for diverse thermodynamic systems. Starting from Legendre invariant metrics of the phase manifold, we derive thermodynamic metrics for the equilibrium manifold whose curvature becomes singular at those points where phase transitions of first and second order occur. We conclude that the thermodynamic curvature of the equilibrium manifold, as defined in geometrothermodynamics, can be used as a measure of thermodynamic interaction in diverse systems with two and three thermodynamic degrees of freedom.
