Zeeman response of d-wave superconductors: Born approximation for impurity and spin-orbit scattering potentials

TL;DR

This paper investigates how impurity and spin-orbit scattering affect the Zeeman response in d-wave superconductors, revealing qualitative differences from s-wave cases through calculations of phase diagrams and density of states.

Contribution

It introduces a Born approximation-based analysis of impurity and spin-orbit effects on the Zeeman response in d-wave superconductors, highlighting unique qualitative differences.

Findings

Spin-orbit interaction alters Zeeman response differently in d-wave vs. s-wave superconductors.

The phase diagram of d-wave superconductors is significantly affected by impurity scattering.

Density of states calculations show distinct features due to spin-orbit effects.

Abstract

The effects of impurity and spin-orbit scattering potentials can strongly affect the Zeeman response of a d-wave superconductor. Here, both the phase diagram and the quasiparticle density of states are calculated within the Born approximation and it is found that the spin-orbit interaction influences in a qualitatively different way the Zeeman response of d-wave and s-wave superconductors.
