Stimulation of tunneling by a high-frequency field: Decay of the zero-voltage state in Josephson junctions Article uri icon

abstract

  • We find the tunneling decay rate D of the zero-voltage states of a Josephson junction driven by a small ac current I1cos, when the dc current is close to the critical one. In the high-frequency limit p (p is the plasma frequency) for a high-Q junction, the amplitude I1 enters into the tunneling exponent with a large exponential factor and lnDI1exp(1.77p). © 1985 The American Physical Society.
