  "comment": "4 pages, Sup.Mat., 3 figures; The paper has been withdrawn because Fig.3 and the claim that (13) is violated are incorrect. Indeed, definitions (12) are equivalent to ours at steady state as pointed out to us by the authors of Ref.[24]. The rest of the paper is correct but the presentation will be reconsidered",

  "abstract": "We propose a thermodynamically consistent definition of heat, energy and work for quantum systems strongly coupled to their surrounding within the framework of nonequilibrium Green functions (NEGF). We show that our heat definition satisfies the second law of thermodynamics when considering systems at steady-state between several reservoirs. For a single quantum level driven by a time-dependent force and in contact with a single reservoir, we derive the quasi-static expression for heat, energy and work. We provide strong evidence that as required by the second law, the reversible heat is always greater then the actual one.",
