摘要
It has been proposed that intermittent weak links between broken symmetry systems can give rise to a novel type of time crystal. Here a practical construction is analyzed in greater detail. For a film-geometry Josephson junction, an applied magnetic field in the junction region can effectively switch on and off the supercurrent. Dissipation can be suppressed and the system is robust against thermal fluctuations. A parallel construction for superfluid $^4$He is also proposed.
