Abstract
We show that a solid-state device, the long Josephson junction, behaves very much like other turbulent systems exhibiting regimes of weak and hard turbulence. Because of the discrete nature of our simulations, we conclude that while a large number of active degrees of freedom are necessary for the existence of turbulence, their number can indeed be small. We show that the transition to the turbulent state is intimately related to the spatiotemporal symmetry breaking and to the existence and breakdown of spontaneous pattern formation in the system.
