Generalized coherent states for solvable quantum systems with degenerate discrete spectra and their nonclassical properties

Abstract

In this paper, the generalized coherent state for quantum systems with degenerate spectra is introduced. Then, the nonclassicality features and number-phase entropic uncertainty relation of two particular degenerate quantum systems are studied. Finally, using the GazeauKlauder coherent states approach, the time evolution of some of the nonclassical properties of the coherent states corresponding to the considered physical systems are discussed. © 2010 Elsevier B.V.
