The dynamic behaviour of the supercurrent in mesoscopic Josephson junc
tions in the presence of a de voltage bias V-0 and quantized electroma
gnetic field is investigated. It is shown that the time evolution of t
he supercurrent exhibits collapse and revival (CR) for SU(1, 1) cohere
nt state (CS), but for coherent states it does not exhibit such phenom
