I-V characteristics of short superconducting nanowires with different bias and shunt: a dynamic approach

摘要

We derived the I-V characteristics of short nanowire in the circuit with andwithout resistive and inductive shunt. For that we used numerical calculationsin the framework of time-dependent Ginzburg-Landau equations with differentrelaxation times for the amplitude and phase dynamics. We also deriveddependence of the I-V characteristics on flux in superconducting quantuminterference device (SQUID) made of such two weak links.
