k -component q-deformed charge coherent states and their nonclassical properties
Xiaolin Liu, C. Quesne, F. Song
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(1,1) generators is given in terms of them. Their nonclassical properties are studied and it is shown that for k⩾3, they exhibit two-mode q-antibunching, but neither SUq(1,1) squeezing, nor one- or two-mode q-squeezing.
