TL;DR

This paper investigates how disordered charge stripes and spin domains influence the electronic properties of high-Tc superconductors, explaining experimental spectra and suggesting fluctuating stripe phases are common in these materials.

Contribution

It provides a unified interpretation of spectroscopic data by linking disordered stripe phases to observed electronic features in high-Tc superconductors.

Findings

Disordered charge stripes explain unusual spectral features.

Fluctuating stripe phases are prevalent in high-Tc superconductors.

Spectroscopic data aligns with neutron scattering and NMR evidence.

Abstract

The consequences of disordered charge stripes and antiphase spin domains for the properties of the high-temperature superconductors are studied. We focus on angle-resolved photoemission spectroscopy and optical conductivity, and show that the many unusual features of the experimentally observed spectra can be understood naturally in this way. This interpretation of the data, when combined with evidence from neutron scattering and NMR, suggests that disordered and fluctuating stripe phases are a common feature of high-temperature superconductors.
