Intrinsic frustration effects in anisotropic superconductors

TL;DR

This paper introduces a framework to analyze how local lattice distortions cause intrinsic frustration in anisotropic superconductors, affecting their properties, especially in layered materials with defects and phonons.

Contribution

It presents a general theoretical framework for understanding intrinsic frustration effects caused by lattice distortions in anisotropic superconductors.

Findings

Lattice distortions induce intrinsic frustration in superconductors.

The framework applies to layered $d$ and $s+d$ superconductors.

Influence of defects and phonons on superconducting properties is analyzed.

Abstract

Lattice distortions in which the axes are locally rotated provide an intrinsic source of frustration in anisotropic superconductors. A general framework to study this effect is presented. The influence of lattice defects and phonons in $d$ and $s+d$ layered superconductors is studied.
