Comment on “ Extraction of work from a single thermal bath in the quantum regime ”
In a recent Letter [1] Allahverdyan and Nieuwenhuizen presented a series of calculations on a quantum system coupled to a quantum heat bath, and made a rather sensational conclusion that the second law of thermodynamics may be violated as a “consequence of quantum coherence in the presence of the slightly off-equilibrium nature of the bath.” However, as we shall explain here, one can use the st...

متن کاملExtraction of work from a single thermal bath in the quantum regime
The stationary state of a quantum particle strongly coupled to a quantum thermal bath is known to be non-Gibbsian, due to entanglement with the bath. For harmonic potentials, where the system can be described by effective temperatures, thermodynamic relations are shown to take a generalized Gibbsian form that may violate the Clausius inequality. For the weakly anharmonic case, a Fokker-Planck-t...

15 صفحه اولfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
