Comments on Extraction of Work from a Single Thermal Bath in the Quantum Regime

arXiv:0706.2835

Abstract

In a PRL [1], the authors claim to show that "the Clausius inequality can be violated, and that it is even possible to extract work from a thermal bath by cyclic variations of a parameter ("perpetuum mobile"), and that the physical cause for this behavior is traced back to quantum coherence in the presence of the nonequilibrium bath (sic)".
