Abstract:
We investigate stationary charge imbalance effect in the system of coupled overdamped Josephson junctions. We show that the stationary charge imbalance in the resistive state brings to a decrease of the Josephson frequency in the junctions of the stack. The formed difference in frequencies leads to the nonuniform switch of the junctions along the stack to the Shapiro step regime in the presence of external electromagnetic radiation.
