Even and odd nonlinear charge coherent states and their nonclassical
properties    [PDF]

X. -M. Liu, B. Li

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 $D$-algebra realization of the SU$_f$(1,1) generators is given in terms of them. They are shown to exhibit SU$_f$(1,1) squeezing and two-mode $f$-antibunching for some particular types of $f$-nonlinearity, but neither one-mode nor two-mode $f$-squeezing.
