Universalities in vortex transport at the melting transition

TL;DR

This paper explains the universal jump in resistance at the vortex melting transition using vortex cuttings and the Hansen-Verlet criterion, showing that this phenomenon is independent of magnetic field and rooted in fundamental universalities.

Contribution

It introduces a novel explanation for the resistance jump at vortex melting based on vortex cuttings and universal structure factor behavior.

Findings

Resistance jump is constant across magnetic fields.

Vortex cuttings explain the resistance change.

Universal structure factor at the freezing transition.

Abstract

We consider the jump in resistance at the melting transition, which is experimentally observed to be constant, independent of magnetic field (vortex density). We present an explanation of this effect based on vortex cuttings, and universalities of the structure factor at the freezing transition (the Hansen-Verlet criterion).
