Josephson Current Counterflow in Atomic Bose-Einstein Condensates
E. Sakellari, N. P. Proukakis, M. Leadbeater +1
Josephson weak links in superconductors can be engineered such that the phase difference across the junction is (-junction),leading to the reversal of the current. The condi…

Vortex dynamics, pinning, and critical currents in a Ginzburg-Landau type-II superconductor
T. Winiecki, C. S. Adams
The dynamics of vortices in a type-II superconductor with defects are studied by solving the time-dependent Ginzburg-Landau equations in two and three dimensions. We show that vort…

Vortex formation in weakly-interacting inhomogeneous Bose condensates
B. Jackson, J. F. McCann, C. S. Adams
We solve the time-dependent Gross-Pitaevskii in 2-D to simulate the flow of an object through a dilute Bose condensate trapped in a harmonic well. We demonstrate vortex formation a…
