Dynamical stripe correlations and the spin fluctuations in cuprate superconductors

TL;DR

This paper proposes that the unusual spin dynamics in cuprate superconductors' normal state originate from a nearly ordered spin system influenced by thermally fluctuating charged domain walls, suggesting a temperature-dependent crossover to a quantum domain wall fluid.

Contribution

It introduces a novel interpretation linking spin dynamics to thermally driven domain wall motion and predicts a crossover to a quantum domain wall fluid at low temperatures.

Findings

Explains temperature dependence of spin dynamics

Suggests a crossover to quantum domain wall fluid at low temperatures

Provides a new perspective on spin fluctuations in cuprates

Abstract

It is conjectured that the anomalous spin dynamics observed in the normal state of cuprate superconductors might find its origin in a nearly ordered spin system which is kept in motion by thermally meandering charged domain walls. `Temperature sets the scale' finds a natural explanation, while a crossover to a low temperature quantum domain wall fluid is implied.
