k-Component q-deformed charge coherent states and their nonclassical properties

Quantum Physics 2009-11-11 v2

Abstract

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 SUq_q(1,1) generators is given in terms of them. Their nonclassical properties are studied and it is shown that for k3k\geq3, they exhibit two-mode q-antibunching, but neither SUq_q(1,1) squeezing, nor one- or two-mode q-squeezing.
