    Density matrix off-diagonal elements

    For a system with time Independent hamiltonian , in the basis of energy eigen kets, every off diagonal element between two kets corresponding to two distinct energy eigen values will oscillate with Bohr Frequency.

    Reference for Axiomatic Quantum Statistical Mechanics

    I have gone through two volumes of Cohen (Quantum Mechanics). Now I need a book on Quantum Statistical Mechanics. The book should use axiomatic formulation using density matrix. Please give me a suggestion. ( I'm also introduced with 2nd quantization slightly) Thanks for any help in advance.
