Quantum Theory of Localized Crystal

Abstract

Abstract A quantum crystal each particle of which is located to a proximity of one lattice point is considered. The causal Green functions at finite temperatures are used. The localized approximation for the iteration of propagator equations is formulated. New type conditions defining parameters of model propagator are proposed. The general method is illustrated with the example of a linear chain.
