Effect of point-contact transparency on coherent mixing of Josephson and transport supercurrents
arXiv:cond-mat/0409411 · doi:10.1103/PhysRevB.69.024516
Abstract
The influence of electron reflection on dc Josephson effect in a ballistic point contact with transport current in the banks is considered theoretically. The effect of finite transparency on the vortex-like currents near the contact and at the phase difference which has been predicted recently \cite{KOSh}, is investigated. We show that at low temperatures even a small reflection on the contact destroys the mentioned vortex-like current states, which can be restored by increasing of the temperature.
