Deconfinement and dissipation in quantum Hall Josephson tunneling

The zero-bias tunneling resonance in quantum Hall bilayer systems is investigated via numerical simulations of the classical two-dimensional XY model with a symmetry-breaking field. Disorder is included in the model and is shown to nucleate strings of overturned spins proliferated through the system...
