Quantum mechanics on a circle: Husimi phase space distributions and semiclassical coherent state propagators
B. Bahr, H. J. Korsch
We discuss some basic tools for an analysis of one-dimensionalquantum systems defined on a cyclic coordinate space. The basic features of the generalized coherent states, the compl…
