摘要： 一种精确且高效的新的方法用于模拟耗散量子系统的动力学。 从费曼和弗纳德的约化密度矩阵的路径积分表达式推导出的随机刘维尔方程，用于描述任何耗散强度和任意低温下的精确动力学。 该方法的实用性通过应用于阻尼谐波振子和浸入低温度欧姆浴中的双势阱系统来展示。 显示英文摘要

摘要： An exact and efficient new method to simulate dynamics in dissipative quantum systems is presented. A stochastic Liouville equation, deduced from Feynman and Vernon's path-integral expression of the reduced density matrix, is used to describe the exact dynamics at any dissipative strength and for arbitrarily low temperatures. The utility of the method is demonstrated by applications to a damped harmonic oscillator and a double-well system immersed in an Ohmic bath at low temperatures.
