Vortex reflection at boundaries of Josephson-junction arrays
T. J. Hagenaars, J. E. van Himbergen, Jorge V. Jose +1
We study the propagation properties of a single vortex in square Josephson-junction arrays (JJA) with free boundaries and subject to an applied dc current. We model the dynamics of…
Quantum effects in a superconducting glass model
T. K. Kopeć, J. V. José
We study disordered Josephson junctions arrays with long-range interaction and charging effects. The model consists of two orthogonal sets of positionally disordered parallel f…
Nonlinear Viscous Vortex Motion in Two-Dimensional Josephson-Junction Arrays
T. J. Hagenaars, P. H. E. Tiesinga, J. E. van Himbergen +1
When a vortex in a two-dimensional Josephson junction array is driven by a constant external current it may move as a particle in a viscous medium. Here we study the nature of this…
Giant Shapiro Resonances in a Flux Driven Josephson Junction Necklace
G. Chu, Jorge V. Jose
We present a detailed study of the dynamic response of a ring of equally spaced Josephson junctions to a time-periodic external flux, including screening current effects. The d…
