摘要
将最近建立的体系-热库纠缠定理(SBET)扩展到非平衡的情形.其中,任意体系与处于不同温度的多个高斯型热库环境相耦合.现有的SBET将体系-热库的纠缠响应函数与体系的局域响应函数联系起来,而扩展的理论则关注通过分子结的非平衡稳态量子输运流.新理论是基于广义Langevin方程建立的,它与量子情形下的非平衡热力学密切相关.
In this work,we extend the recently established system-bath entanglement theorem(SBET)to the nonequilibrium scenario,in which an arbitrary system couples to multiple Gaussian bath environments at dif⁃ferent temperatures.The existing SBET connects the entangled system-bath response functions to those of local systems,while the extended theory is concerned with the nonequilibrium steady-state quantum transport cur⁃rent through molecular junctions.The new theory is established on the basis of the generalized Langevin equa⁃tion,with a close relation to nonequilibrium thermodynamics in the quantum regime.
