Charge inhomogeneity coexisting with large Fermi surfaces

TL;DR

This paper explores how charge inhomogeneity in cuprates can coexist with large Fermi surfaces, revealing a dual nature of electronic structures that combines Fermi-liquid behavior with one-dimensional features.

Contribution

It demonstrates the compatibility of stripe order with large Fermi surfaces and introduces the concept of a pseudo Fermi surface arising from charge inhomogeneity.

Findings

Stripe order can coexist with large Fermi surfaces in cuprates.

Charge inhomogeneity leads to a pseudo Fermi surface with one-dimensional characteristics.

The results reconcile Fermi-liquid behavior with stripe-induced inhomogeneity.

Abstract

We discuss how stripes in cuprates can be compatible with a Fermi-liquid-like Fermi surface and, at the same time, they give rise to a one-dimensional-like pseudo Fermi surface in the momentum distribution function.
