平衡态可以用纯量子态表示,我们称之为热纯量子(TPQ)态。我们提出了一种新的 TPQ 状态以及获取它的简单方法。 TPQ 态的单一实现足以计算有限温度下量子系统的所有统计力学特性,包括相关函数和真正的热力学变量。
An equilibrium state can be represented by a pure quantum state, which we call a thermal pure quantum (TPQ) state. We propose a new TPQ state and a simple method of obtaining it. A single realization of the TPQ state suffices for calculating all statistical-mechanical properties, including correlation functions and genuine thermodynamic variables, of a quantum system at finite temperature.
