摘要翻译:
单位圆上电荷中性双组分库仑等离子体的边界sine-Gordon理论与热力学之间存在着一定的联系。另一方面,最近发现膜衰变的开弦worldsheet描述可以与单组分等离子体的热力学平衡点序列有关。这里我们考虑一个不同的衰变过程,它是由时间边界sine-Gordon理论专门描述的。在非中性双组分库仑等离子体的热平衡点空间中,时间演化可以映射为一维曲线。我们计算了系统的自由能,发现它沿着曲线单调递减,定义了一个热力学时间箭头。

英文摘要:
It has long been known that there is a relation between boundary sine-Gordon theory and thermodynamics of charge neutral two-component Coulomb plasma on a unit circle. On the other hand, recently it was found that open string worldsheet description of brane decay can be related to a sequence of points of thermodynamic equilibrium of one-component plasma. Here we consider a different decay process which is specifically described by the timelike boundary sine-Gordon theory. We find time evolution to be mapped to a one-dimensional curve in the space of points of thermal equilibrium of a non-neutral two-component Coulomb plasma. We compute the free energy of the system and find that along the curve it is monotonously decreasing, defining a thermodynamic arrow of time.
