Bosonization and Renormalization Group Treatment of Quantum Heisenberg Model

摘要

A novel method is introduced for studying the critical behaviour of isotropic and anisotropic quantum Heisenberg models. It consists of an exact bosonization of the spin operators and subsequent application of the renormalization group treatment. It is found that the quantum and classical Heisenberg models belong to the same universality class. (Atomindex citation 09:366266)
