Phys. Rev. E 79, 056224 (2009) [11 pages]Emergence of dissipative structures in current-carrying superconducting wiresReceived 17 February 2009; published 26 May 2009 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 a structure to be self-sustainable. Stability and the conditions for experimental observation of this phenomenon are also discussed. © 2009 The American Physical Society URL:
