Domain Walls Motion and Resistivity in a Fully-Frustrated Josephson Array

TL;DR

This paper demonstrates through numerical analysis that the resistivity in a fully-frustrated Josephson-junction array is primarily caused by domain wall motion in the vortex lattice, not by individual vortex movement.

Contribution

It reveals the dominant role of domain wall dynamics in resistivity, providing new insights into vortex behavior in Josephson arrays.

Findings

Resistivity is due to domain wall motion, not single vortices.

Domain walls significantly influence the electrical properties.

Numerical methods effectively identify vortex lattice dynamics.

Abstract

It is identified numerically that the resistivity of a fully-frustrated Josephson-junction array is due to motion of domain walls in vortex lattice rather than to motion of single vortices.
