FORMULATION OF QUANTUM STATISTICAL MECHANICS AS A FUNCTION OF THE OCCUPATION NUMBERS
Roger Balian, Claude Bloch, C. De Dominicis
Abstract
The introduction of a self-consistent potential, the use of representation diagrams dependent on'time between 0 and beta , and the application of an algebraic theorem on the operators of creation and absorption permit the simple expression of the thermodynamic magnitudes as a function of the occupation number for a quantum system.
