- Authors: Peng-Li Du, Zi-Hao Chen, Yu Su, Yao Wang, Rui-Xue Xu, YiJing Yan
- Abstract summary: We extend the recently established system-bath entanglement theorem (SBET) to the nonequilibrium scenario.
While the existing SBET connects the entangled system-bath response functions to those of local systems, the extended theory is concerned with the nonequilibrium steady-state quantum transport current through molecular junctions.

- Abstract: In this work, we extend the recently established system-bath entanglement
theorem (SBET) [J. Chem. Phys. 152, 034102 (2020)] to the nonequilibrium
scenario, in which an arbitrary system couples to multiple Gaussian baths
environments at different temperatures. While the existing SBET connects the
entangled system-bath response functions to those of local systems, 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.

Environments in quantum thermodynamics usually take the role of heat baths.
We show that within the same model, the environment can take three different thermodynamic roles.

Quantum work fluctuation theorem (FT) commonly requires the system initially prepared in an equilibrium state.
Here, I initialize the system in a near-equilibrium state, and derive the corresponding modified Jarzynski equality by using the perturbation theory.
I also verify my theoretical results by considering a concrete many-body system, and reveal a fundamental connection between quantum critical phenomenon and near-equilibrium state at really high temperature.
