  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 coupled to external super-baths is compared with consideration of
thermodynamics of a system strongly coupled to its baths. We analyze both
approaches from the NEGF perspective and argue that the latter yields a
possibility of thermodynamic formulation consistent with dynamical (quantum
transport) description.
