TL;DR

This paper investigates fluxon dynamics in corner junctions with triplet pairing symmetry, revealing complex fluxon interactions and propagation modes through numerical analysis of I-V characteristics.

Contribution

It provides the first detailed numerical analysis of fluxon motion and I-V characteristics in triplet superconductor junctions with corner geometry.

Findings

Fluxons interact with fractional fluxons but do not change position or polarity.

Multiple modes of multifluxon propagation are observed.

Small length limits introduce additional steps in the I-V diagram.

Abstract

We present the numerical solutions for the I-V characteristics, and describe the motion of fluxons in a frustrated Josephson junction made of an unconventional triplet superconductor and an s-wave superconductor. In the inline geometry, and long length limit the moving integer fluxon interacts with the bound fractional fluxon but is not able to change its position or polarity. We observe different modes of multifluxon propagation. In the small length limit the moving fluxon is a combination of the stable solutions that exist in the static case and additional steps are introduced in the I-V diagram.
