“…There we observe several features which are characteristic to PSLs: (1) a voltage jump from zero voltage at some critical current; (2) all resistive branches have approximately the same excess current (given by the intersection of their slopes with current axis); (3) the differential resistance of a resistive branch is proportional to its number. This behavior differs, for example, from the propagation of flux jumps [10]. Each voltage jump in IV curve corresponds to a generation of an additional PSL in the film.…”

Josephson Behavior of Phase-Slip Lines in Wide Superconducting Strips

Phase-slip lines can be viewed as dynamically created Josephson junctions in a homogeneous superconducting film. In contrast to phase-slip centers, phase-slip lines occur in wide superconducting strips, where the order parameter may vary in two dimensions. We investigated phase-slip lines in two different materials using several methods. We observed Shapiro steps under microwave radiation, which shows that the frequency of the order parameter oscillation is equal to Josephson frequency. A periodic oscillation of a critical current versus the applied magnetic field was found in strips with a hole in the middle. The latter effect provides a clear evidence of macroscopic quantum interference across a phase-slip line. We have used low temperature scanning laser microscopy to visualize the phase-slip lines and to distinguish them from possible local inhomogeneities in the films.

An exact solution of a new superconducting state is obtained which exists for DC currents larger than the critical current in thin wires. The order‐parameter is zero at all times at certain points in the whisker, thereby permitting the phase to slip at a constant rate, a consequence of which is a de potential difference between the separate singly‐connected superconducting regions. These solutions are periodic in space and lead to voltage steps in the do voltage‐current characteristic. It is proven in the limit when the zeros of the order‐parameter are far apart that these solutions are stable.
