Pseudogap and short-range antiferromagnetic correlation controlled Fermi surface in underdoped cuprates: From Fermi arc to electron pocket

TL;DR

This paper investigates how short-range antiferromagnetic correlations influence the Fermi surface in underdoped cuprates, explaining the absence of electron pockets in experiments and analyzing quantum oscillation phenomena.

Contribution

It introduces a model showing the impact of short-range antiferromagnetic correlations on Fermi surface features, particularly the smearing of electron pockets in underdoped cuprates.

Findings

Electron pockets are smeared out by short-range antiferromagnetic correlations.

The Hall resistance behavior depends on scattering effects and superconductivity.

Electron pockets may be undetectable in ARPES due to correlation effects.

Abstract

Motivated by recent quantum oscillation observations in the underdoped high-temperature superconductors, the effect of the short-range antiferromagnetic correlations on the electronic properties of the short-ranged d-density wave state is investigated. At intermediate d-density wave correlations, the cross section of the energy dispersion at the Fermi energy consists of hole pockets and an electron pocket. It is argued that the electron pocket feature is smeared out by the effect of the short-range antiferromagnetic correlation, which could be the reason why any electron pockets have never been observed in the angle resolved photoemission experiments. The Hall resistance is calculated for the system with the electron band and the hole band using a finite temperature formula assuming Dirac fermion spectrum for the latter. It is argued that the scattering effect in the hole band should be anomalously large or much suppressed by superconductivity correlations and/or vortex contributions to explain the recent quantum oscillation observations.
