Angle-resolved photoemission spectra in the cuprates from the d-density wave theory
Sudip Chakravarty, Chetan Nayak, Sumanta Tewari
Abstract
Angle-resolved photoemission spectra present two challenges for the d-density wave (DDW) theory of the pseudogap state of the cuprates: (1) hole pockets near (π/2,π/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.
