Proof of the Ergodic Theorem and the H-Theorem in Quantum Mechanics

History and Philosophy of Physics 2010-12-02 v2 Statistical Mechanics Quantum Physics

Abstract

It is shown how to resolve the apparent contradiction between the macroscopic approach of phase space and the validity of the uncertainty relations. The main notions of statistical mechanics are re-interpreted in a quantum-mechanical way, the ergodic theorem and the H-theorem are formulated and proven (without "assumptions of disorder"), followed by a discussion of the physical meaning of the mathematical conditions characterizing their domain of validity.
