Based on a recent progress in nonequilibrium statistical mechanics ofinfinitely extended quantum systems, a nonequlibrium steady state (NESS) isconstructed for a single-level quantum dot interacting with two free reservoirsunder less general but more practically useful conditions than the previousworks. As an example, a model of an Ahoronov-Bohm ring with a quantum dot isstudied in detail. Then, NESS is shown to be regarded as a MacLennan-Zubarevensemble. A formal relation between response and correlation at NESS is derivedas well.Comment: submitted to Progress of Theoretical Physic
