摘要：

A new kind of even and odd nonlinear coherent states (EONLCSs) is introduced. Using the Pegg-Barnett formalism of phase operator we study the phase probability distributions of the new kind of EONLCSs. The numerical computation results show that the phase probability distributions for the new EONLCSs can clearly exhibit the different features of quantum interference and distinct from those of the ordinary even and odd coherent states (EOCSs) and EONLCSs. Based on the phase probability distributions we investigate the phase and number squeezing of the new EONLCSs. It is found that these states exhibit number squeezing for different ranges of the parameter vertical bar lambda vertical bar. (C) 2007 Elsevier B.V. All rights reserved.
