Vortex Dynamics in Networks of Josephson Junctions
Since the proposal by Josephson1 in 1962 that a tunnel Junction, i.e. two superconductors weakly coupled through an oxide barrier, should show a zero-voltage supercurrent due to the tunneling of Cooper pairs, this system has been studied with unending enthusiasm. In particular, initiated by Leggett,2 the last decade has seen a remarkable activity in a field which is often called Quantum Mechanics of Macroscopic Variables;3 experiments on small Josephson junctions at low temperature are found to be in excellent agreement with theoretical predictions.
