Unidirectionally shifted shadow arcs in La_{2-x}Sr_xCuO_4 explained

TL;DR

This paper explains the origin of faint shadow arcs in La_{2-x}Sr_xCuO_4 as resulting from lattice distortions caused by edge dislocations introduced during sample cleaving.

Contribution

It provides a specific explanation for the unidirectional shifted shadow arcs observed in the material, linking them to lattice distortions from dislocations.

Findings

Shadow arcs are caused by lattice distortions from edge dislocations.

Unidirectional shift of shadow arcs is explained by dislocation-induced lattice distortion.

Lattice distortion from cleaving introduces the observed shadow arcs.

Abstract

The observed faint shadow arcs, shifted unidirectionally from primary Fermi arcs, are caused by lattice distortion from edge dislocations introduced by cleaving the samples.
