Abstract

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 different 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 current through molecular junctions. The new theory is established on the basis of the generalized Langevin equation, with a close relation to nonequilibrium thermodynamics in the quantum regime.
