摘要：

Supercurrent fluctuation of a mesosocopic Josephson junction (MJJ) in the pre-sense of a dc static voltage and a time-varying quantized electromagnetic field (QEMF) is investigated. It is shown that the fluctuation of supercurrent in the MJJ exhibits periodical oscillations with a periodicity which depends upon the rate of the classical static external voltage and the frequency of the QEMF.
