Abstract
Dynamic behavior of a mesoscopic Josephson junction in the presence of a two-mode quantized electromagnetic field is investigated. It is shown that the currentvoltage- step structures depend apparently on the two basic frequencies of the two-mode field. The voltage jumps are generally not equidistant. It is also shown that for the correlated two-mode squeezed state the time evolution of the supercurrent exhibits quantum collapse and revival(CR) phenomenon, while for the noncorrelated two-mode coherent state the phenomenon does not occur.
