Abstract

The (over)completeness of even and odd nonlinear charge coherent states is proved and their generation explored. They are demonstrated to be generalized entangled nonlinear coherent states. A DD-algebra realization of the SUf_f(1,1) generators is given in terms of them. They are shown to exhibit SUf_f(1,1) squeezing and two-mode ff-antibunching for some particular types of ff-nonlinearity, but neither one-mode nor two-mode ff-squeezing.
