“Experiments on Non-equilibrium Josephson Systems in One and Two Dimensions”
Experimental progress in quantum computing has yielded exciting new tools for probing and manipulating superconductors. I will discuss our recent work on driven behavior of 1D and 2D Josephson junction arrays. In one dimension, I will present recent studies of the nonlinear response of both insulating and superconducting systems, making some connections to Luttinger liquids and nonlinear optics. In two dimensions, I will show our discovery of non-equilibrium microwave radiation and non-equilibrium noise scaling near the superconductor-insulator quantum phase transition. In both cases, I will attempt to highlight outstanding puzzles where theoretical input is needed.
