On the Stability of the Superconducting State in Quasi-One-Dimensional Superconducting Nanowires

Abstract

The dynamics of destroying of superconducting state in quasi-one-dimensional currentcarrying nanowires with the help generalized time-depended Ginzburg–Landau equations are studied. This equation may describe a new type of superconducting materials with the first-order superconducting phase transition. It has been shown that the superconducting nanowires for such materials admit more higher value for a current without destroying the zero-resistance state. It has been shown demonstrate also that for current-carrying filaments the value of current to create phase-slip centres and non zero resistance state, is higher than for such a current for ordinary superconducting materials with the second-order superconducting phase transition.
