Complex Spectral Representation of the Liouvillian and Kinetic Theory in Nonequilibrium Physics

Tomio Petrosky.

in Progress of Theoretical Physics

March 2010; p ublished online March 2010 .

Journal Article. Subjects: Quantum Physics; Classical Mechanics. 0 words.

Kinetic theory in nonequilibrium statistical physics is discussed in terms of the complex spectral representation of the Liouvillian for quantum systems. We show that the collision operator...

Eulerian and Newtonian dynamics of quantum particles

S. A. Rashkovskiy.

in Progress of Theoretical and Experimental Physics

P ublished online June 2013 .

Journal Article. Subjects: Quantum Physics; Classical Mechanics; Mathematical and Statistical Physics. 8920 words.

We derive the classical equations of hydrodynamics (the Euler and continuity equations), from which the Schrödinger equation follows as a limit case. It is shown that the statistical...
