Dressing of the charge carriers in high-Tc superconductors

TL;DR

This paper reviews ARPES studies on how charge carriers in high-Tc superconductors are affected by interactions, focusing on their spectral and self-energy functions in different states and specific materials.

Contribution

It provides a comprehensive review of recent ARPES findings on charge carrier dressing in high-Tc cuprates, highlighting differences at nodal and antinodal points.

Findings

Charge carriers exhibit distinct self-energy features in normal and superconducting states.

Differences in dressing are observed between nodal and antinodal regions.

Results are specifically detailed for Bi2Sr2CaCu2O8+δ.

Abstract

In this contribution we review recent ARPES results on the dressing of the charge carriers in high-temperature superconductors. After an introduction into the cuprates and their electronic structure, ARPES, the spectral function and the self-energy function in the normal state and in the superconducting state is discussed.. Finally results on the dressing of the charge carriers in the system Bi2Sr2caCu2O7 at the nodal and the antinodal point are presented.
