Resonance reduction of the lifetime of the metastable state of tunnel junctions
Abstract
The lifetime of a metastable current state of a tunnel junction is reduced under the action of a weak microwave perturbation. The dependence of the lifetime on pumping frequency is found and describes the experimental data. At a very highQ-factor, frequent sharp dips appear in the dependence of the lifetime on pumping frequency. These dips are connected with the quantum properties of the phase of the order parameter.
