# Statistical Mechanics and the Physics of Many-Particle Model Systems

@inproceedings{Kuzemsky2011StatisticalMA, title={Statistical Mechanics and the Physics of Many-Particle Model Systems}, author={Alexander L. Kuzemsky}, year={2011} }

The development of methods of quantum statistical mechanics is considered in light of their applications to quantum solid-state theory. We discuss fundamental problems of the physics of magnetic materials and the methods of the quantum theory of magnetism, including the method of two-time temperature Green’s functions, which is widely used in various physical problems of many-particle systems with interaction. Quantum cooperative effects and quasi-particle dynamics in the basic microscopic…
