B. Shao et al., COLLAPSE AND REVIVAL OF SUPERCURRENT IN MESOSCOPIC JOSEPHSON-JUNCTIONS LIN THE PRESENCE OF NONCLASSICAL ELECTROMAGNETIC-FIELD, Chinese Physics Letters, 14(12), 1997, pp. 905-907
Dynamic behavior of the supercurrent in a mesoscopic Josephson junctio
n in the presence of a nonclassical electromagnetic field is investiga
ted. It is shown that for the squeezed state the time evolution of the
supercurrent can exhibit quantum collapse and revival phenomenon, whi
le for the coherent state the phenomenon does not occur.
