研究了受驱动量子朗之万系统在非平衡定态下的能量耗散。研究了能量耗散流对热环境的影响，利用系统变量的自相关函数，得到了平均能量耗散率的一般公式。这导致了将涨落-响应关系的破坏与能量耗散率联系起来的等式的一般表达式，其经典版本首先由Harada和Sasa研究。
Energy dissipation in a nonequilibrium steady state is studied in driven quantum Langevin systems. We study energy dissipation flow to thermal environment, and obtain a general formula for the average rate of energy dissipation using an autocorrelation function for the system variable. This leads to a general expression of the equality that connects the violation of the fluctuation-response relation to the rate of energy dissipation, the classical version of which was first studied by Harada and Sasa.
