Large deviations and mean-field quantum systems

authored by

R. F. Werner

Abstract

An expository account is given of the equilibrium thermodynamics of mean-field quantum systems. It is shown how this theory can be understood as the quantum generalization of the theory of Large Deviations as applied to systems of identically distributed independent random variables. Special emphasis is given to inhomogenous and site-random systems. Some new limit theorems are proven, concerning systems with Hamiltonians which are only bounded from below, and not from above, and also are allowed to increase with the system size.
