Fe b 20 07 Thermodynamics with generalized ensembles : The class of dual orthodes

  title={Fe b 20 07 Thermodynamics with generalized ensembles : The class of dual orthodes},
  author={Michele Campisi},
We address the problem of the foundation of generalized ensembles in statistical physics. The approach is based on Boltzmann’s concept of orthodes. These are the statistical ensembles that satisfy the heat theorem, according to which the heat exchanged divided by the temperature is an exact differential. This approach can be seen as a mechanical approach alternative to the well established information-theoretic one based on the maximization of generalized information entropy. Our starting point… CONTINUE READING
