Cuprate Fermi Orbits and Fermi Arcs: The Effect of Short-Range Antiferromagnetic Order

Abstract

We consider the effect of a short antiferromagnetic correlation length ξ on the electronic band structure of the underdoped cuprates. Starting with a Fermi-surface topology consistent with magnetic-quantum-oscillation data, we show that a reduced ξ gives an asymmetric broadening of the quasiparticle dispersion, resulting in simulated ARPES data very similar to those observed in experiment. Predicted features include “Fermi arcs” close to ak=(π/2,π/2), where a is the in-plane lattice parameter, without the need to invoke a d-wave pseudogap order parameter. The statistical variation in the k-space areas of the reconstructed Fermi-surface pockets causes the quantum oscillations to be strongly damped, even in very strong magnetic fields, in agreement with experiment.
