Angle-resolved photoemission spectra in the cuprates from the d-density wave theory -: art. no. 100504

Angle-resolved photoemission spectra present two challenges for the d-density wave theory of the pseudogap state of the cuprates: (1) Hole pockets near (pi/2,pi/2) are not observed, in apparent contradiction with the assumption of translational symmetry breaking, and (2) There are no well-defined quasiparticles at the antinodal points, in contradiction with the predictions of mean-field theory of this broken-symmetry state. Here, we show how these puzzles can be resolved.
