摘要
Supercurrent fluctuation of a mesoscopic Josephson jutiction(MJJ)in the presence of a de static voltage and a time-varying quantized electromagnetic field(QEMF)is investigated.It is shown thm the fluctuation of supercurrent in the MJJ exhibits periodical oscillations with a periodicity shich depends upon the rate of the classical static external voltage and the frequency of the QEMF.
