On the Dynamics of Generalized Coherent States. I. Exact and Stable Evolution

B. A. Nikolov, D. A. Trifonov

摘要:

利用含时运动积分方法和Klauder方法研究量子力学与经典力学的关系,研究了量子系统广义相干态的精确稳定演化.证明了对任何量子系统都可以构造出与李群G的幺正表示有关的过完备态族(OFS),并指出了利用李群G作为动力学对称群的可能性.建立了OFS与量子测量理论的联系。

英文摘要:

The exact and stable evolutions of generalized coherent states (GCS) for quantum systems are considered by making use of the time-dependent integrals of motion method and of the Klauder approach to the relationship between quantum and classical mechanics. It is shown that one can construct for any quantum system overcomplete family of states (OFS), related to the unitary representations of the Lie group G by means of integral of motion generators, and the possibility of using this group as a dynamical symmetry group is pointed out. The relation of the OFS with quantum measurement theory is also established.
