Instability at a nonequilibrium superconducting junction
Larkin A. I. , Ovchinnikov Yu. N.
The tunnel injection of electrons from an auxiliary junction at a Josephson junction is accompanied by an instability. The threshold for the instability and the state that arises are determined by both the normal current and the dissipative part of the Josephson current. The average value of the voltage that arises is found, as is the amplitude of the alternating voltage.
