A Green’s function perspective on the nonequilibrium thermodynamics of open quantum systems strongly coupled to baths

We give nonequilibrium Green's function (NEGF) perspective on thermodynamics formulations for open quantum systems strongly coupled to baths. Scattering approach implying thermodynamic consideration of a super-system (system plus baths) weakly external super-baths is compared with system its analyze both approaches from the NEGF and argue that latter yields possibility formulation consistent dynamical (quantum transport) description.
