Material and doping dependence of the nodal and anti-nodal dispersion renormalizations in single- and multi-layer cuprates

TL;DR

This paper reviews how electron-phonon interactions influence electronic dispersion in cuprates, highlighting material and doping dependence, and suggesting that bosonic renormalizations are primarily due to lattice coupling effects.

Contribution

It provides a comprehensive review of bosonic renormalization effects in cuprates, emphasizing the role of electron-phonon coupling across different materials and doping levels.

Findings

Renormalization effects vary with material and doping.

Electron-phonon coupling explains the observed dispersion renormalizations.

Material dependence is linked to differences in electron-phonon interactions.

Abstract

In this paper we present a review of bosonic renormalization effects on electronic carriers observed from angle-resolved photoemission spectra in the cuprates. We specifically discuss the viewpoint that these renormalizations represent coupling of the electrons to the lattice, and review how the wide range of materials dependence, such as the number of CuO$_2$ layers, and the doping dependence can be straightforwardly understood as arising due to novel electron-phonon coupling.
