Use of methods of quite positive semigroups theory in research of open spin systems dunamics

By Artemyev Alexander Yurevich

Abstract

The paper is concerned with open spin systems. The aim of the paper is to develop bases of a sequential, agreed with main principles of quantum mechanics, theory of spin systems anisotropic relaxation. For the first time a sequential approach to the development of an anisotropic relaxation theory for spin systems that is logically related with main principles of the quantum mechanics has been offered. The classification of these equations according to groups of surrounding symmetries has been given. Summarizing of equations for spin systems with failure has been found. The developed approach to the description of relaxation processes in open spin systems is used to study quantum pulsations phenomenon of light polarization caused by the surrounding anisotropy. It has been shown that this phenomenon is realized, if the group SO(2) is a group of symmetriesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
