【 摘 要 】

In this paper we study the quantum phase properties of nonlinear coherent states and solvable quantum systems with discrete spectra using the Pegg-Barnett formalism in a unified approach. The presented procedure will then be applied to few special solvable quantum systems with known discrete spectrum as well as to some new classes of nonlinear oscillators with particular nonlinearity functions. Finally the associated phase distributions and their nonclasscial properties such as the squeezing in number and phase operators have been investigated, numerically. (C) 2009 Elsevier B.V.
