Topological insulators are unique physical structures that are insulators in their bulk, but support currents at their edges which can be unidirectional and topologically protected from scattering on disorder and inhomogeneities. Photonic…
We study quasi-one dimensional wires of two-band superconductors driven by an electrical current. We find that the onset of dissipation can occur with the nucleation of time-connected phase slips (t-PS). The topological structure of the…
