# Manifestations of spin-orbit coupling in a cuprate superconductor

## TL;DR

This paper investigates spin-orbit coupling effects in cuprate superconductors, inspired by recent ARPES data on Bi2212, and explores how these effects manifest in both normal and superconducting states, including the spin-Hall and Edelstein effects.

## Contribution

It introduces a framework for observing spin-orbit coupling in cuprates through local inversion symmetry breaking and analyzes related spin-driven phenomena.

## Key findings

- Identification of spin-orbit coupling signatures in cuprates
- Analysis of spin-Hall and Edelstein effects in superconducting states
- Connection between ARPES observations and theoretical models

## Abstract

Exciting new work on Bi2212 shows the presence of non-trivial spin-orbit coupling effects as seen in spin resolved ARPES data [Gotlieb et al., Science, 362, 1271-1275 (2018)]. Motivated by these observations we consider how the picture of spin-orbit coupling through local inversion symmetry breaking might be observed in cuprate superconductors. Furthermore, we examine two spin-orbit driven effects, the spin-Hall effect and the Edelstein effect, focusing on the details of their realizations within both the normal and superconducting states.
