k-Component q-deformed charge coherent states and their nonclassical properties
k-Component q-deformed charge coherent states are constructed, their
(over)completeness proved and their generation explored. The q-deformed charge
coherent states and the even (odd) q-deformed charge coherent states are the
two special cases of them as k becomes 1 and 2, respectively. A D-algebra
realization of the SU(1,1) generators is given in terms of them. Their
nonclassical properties are studied and it is shown that for , they
exhibit two-mode q-antibunching, but neither SU(1,1) squeezing, nor one- or
two-mode q-squeezing.Comment: LaTeX, 29 pages, 2 Postscript figures, minor change
