Near doping-independent pocket area from an antinodal Fermi surface instability in underdoped high temperature superconductors
arXiv:1108.1511 · doi:10.1103/PhysRevLett.107.186408
Abstract
Fermi surface models applied to the underdoped cuprates predict the small pocket area to be strongly dependent on doping whereas quantum oscillations in YBa2Cu3O6+x find precisely the opposite to be true; seemingly at odds with the Luttinger volume. We show that such behavior can be explained by an incommensurate antinodal Fermi surface nesting-type instability; further explaining the doping-dependent superstructures seen in cuprates using scanning tunneling microscopy. We develop a Fermi surface reconstruction scheme involving orthogonal density waves in two-dimensions and show that their incommensurate behavior requires momentum-dependent coupling. A co-operative modulation of the charge and bond-strength is therefore suggested.
