The time reversal invariant fractional Josephson effect
One of the most basic consequences of topological superconductivity is the fractional Josephson effect, which arises due to the coherent tunneling of single electrons between two superconductors, leading to an ac Josephson effect with half the usual Josephson frequency. In this paper we will review the theoretical and experimental foundations of topological superconductivity and the fractional ...
متن کاملFractional Solitons in Excitonic Josephson Junctions
The Josephson effect is especially appealing to physicists because it reveals macroscopically the quantum order and phase. In excitonic bilayers the effect is even subtler due to the counterflow of supercurrent as well as the tunneling between layers (interlayer tunneling). Here we study, in a quantum Hall bilayer, the excitonic Josephson junction: a conjunct of two exciton condensates with a r...

متن کاملDissipation in a simple model of a topological Josephson junction.
The topological features of low-dimensional superconductors have created a lot of excitement recently because of their broad range of applications in quantum information and their potential to reveal novel phases of quantum matter. A potential problem for practical applications is the presence of phase slips that break phase coherence. Dissipation in nontopological superconductors suppresses ph...
متن کاملDeconfinement 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, with unpaired vortices and antivortices at their end points. This string glass state supports l...
