Coherent states: Theory and some Applications

摘要: In this review, a general algorithm for constructing coherent states of dynamical groups given quantum physical system is presented. The result that, group, the are isomorphic to coset space group geometrical space. Thus topological and algebraic structure as well associated can be extensively discussed. addition, quantum-mechanical phase-space representation constructed via coherent-state theory. Several useful methods employing study phenomena quantum-dynamic systems, such path integral, variational principle, classical limit, thermodynamic limit mechanics, described.
