Description
A mathematical model is presented for the retardation of the Werthamer functional for the Josephson tunneling junction to treat the current controlled case. Computational results concerning the current-voltage characteristic make visible an enhanced hysteresis due to the nonlinear frequency response of the tunneling current. In addition, the irreversible flux transition in a SQUID is analyzed: the flux quantum transition time is found to be shorter than predicted by quasiadiabatic models
