Transient Oscillations

We present evidence for a close analogy between the nonlinear behaviour of a pulsed microwave-driven Josephson junction at low temperature and the experimentally observed behaviour of Josephson systems operated below the quantum transition temperature under similar conditions. We specifically address observations of Ramsey-type fringe oscillations, which can be understood in classical nonlinear dynamics as results of slow transient oscillations in a pulsed microwave environment. Simulations are conducted to mimic experimental measurements by recording the statistics of microwave-induced escape events from the anharmonic potential well of a zero-voltage state. Observations consistent with experimentally obtained Ramsey-type oscillations are found in the classical model.

Spatial Inhomogeneities

The spontaneous emergence of enhanced responses and local orders are properties often associated with complex matter where nonlinearities and spatial inhomogeneities dominate. We discuss these phenomena in quantum devices realized with superconducting Josephson junction networks and cold atoms in optical lattices. We evidence how the pertinent engineering of the network's shape induces the enhancement of the zero-voltage Josephson critical currents in superconducting arrays as well as the emergence of spatially localized condensates for cold atoms in inhomogeneous optical lattices.

Zero Voltage

The current–voltage characteristics and voltage oscillations of evaporated, superconducting weak-link junctions have been investigated. The zero-voltage current variation with temperature is shown to be similar to that for a Josephson junction. A simple theory based on part of the superconductor switching normal enables us to explain the voltage snapback. A model based on thermal instabilities due to bubbles in the liquid helium in contact with the junction has been used to explain the voltage oscillations.
