Contribution

It introduces a new method to identify vortex and skyrmion structures in nematic superconductors beyond traditional symmetry assumptions.

Findings

Nematic superconductors form distinctive skyrmion stripe structures.

Skyrmion structures produce a double peak in the field distribution.

The approach improves the accuracy of field distribution determination for muon spin rotation.

Abstract

We investigate the magnetic response of nematic superconductors, presenting a new approach to find vortex and skyrmion structures beyond symmetry-constraining ans\"atze. Using this approach we show that nematic superconductors form distinctive skyrmion stripes. Our approach lends itself to accurate determination of the field distribution for muon spin rotation probes. We use this to show that the skyrmion structure manifests as a double peak in the field distribution, markedly different from the signal of standard vortex lattices.
