【Abstract】 The lnteraction of mesoscopic Josephson junction with a single mode quantum light field was investigated. It is found that the expectation value and the super current fluctuation may have Shapiro steps. The static super current flows in the positive or negative direction, which relates to the phase of the light field.更多还原
