NONLINEAR MOBILITY IN A SUPERCONDUCTING TUNNEL JUNCTION INVOLVING VARIATIONAL WAVE FUNCTIONS
Keyword(s):
We consider the effect of dissipation on the nonlinear mobility in a superconducting tunnel junction. Using a variational approach, the critical mobility crucially depends on the coupling to the ohmic bath. At ultrasmall capacitances, good agreement is found with decay rates diagrams. The current model could be developed in other contexts, such as that of a ferroelectric capacitor, as proposed by Widom and Clark (Phys. Rev.B30, 1205 (1984)).
