Emergence of Dissipative Structures in Current-Carrying Superconducting Wires (Postprint)

Abstract

We discuss the emergence of a spontaneous temperature and critical current spatial modulation in current-carrying high-temperature superconducting wire. The modulation of the critical current along the wire on a scale of 3-10 mm forces a fraction of the transport current to crisscross the resistive interface between the superconducting film and normal metal stabilizer attached to it. This generates additional heat that allows such structure to be self-sustainable. Stability and the conditions for experimental observation of this phenomenon are also discussed.
