    "abstract": "It is often claimed, that from a quantum system of d levels, and entropy S\nand heat bath of temperature T one can draw kT(ln d -S) amount of work.\nHowever, the usual arguments based on Szilard engine are not fully rigorous.\nHere we prove the formula within Hamiltonian description of drawing work from a\nquantum system and a heat bath, at a cost of entropy of the system. We base on\nthe derivation of thermodynamical laws and quantities in [R. Alicki, J. Phys.\nA, 12, L103 (1979)] within a weak coupling limit. Our result provides fully\nphysical scenario for extracting thermodynamical work from quantum correlations\n[J. Oppenheim et al. Phys. Rev. Lett. 89, 180402 (2002)]. We also derive\nLandauer principle as a consquence of second law within the considered model.",
