| Abstract: | The non-equilibrium
ensembles method has been applied to Boltzmann quantum-kinetic equation. We
used the quantum-kinetic equation governing the density matrix, which has been
proposed by Ogul and Eren, J Chem Phys,
105 (1996) 7664. The non-equilibrium quantum-mechanical ensemble can be
constructed in terms of non-equilibrium entropy, Boltzmann entropy, constrained
by the quantum Boltzmann equation as a dynamical equation of motion, which has
governed the time evolution of non-equilibrium density matrix. The
quantum-mechanically non-equilibrium partition function has been obtained. The
conjuncture with the traditional irreversible thermodynamics has been shown. |
