Phys. Rev. B 68, 180506(R) (2003) [4 pages]Theory of quasiparticle interference patterns in the pseudogap phase of the cuprate superconductors
A method is proposed to test for the nature of the pseudogap phase in cuprates using the recently developed technique of Fourier-transform scanning tunneling spectroscopy. We show that the observed quasiparticle interference patterns depend critically on the quasiparticle coherence factors, making it possible to distinguish between the pseudogap dominated by superconducting fluctuations from the pseudogap dominated by various particle-hole condensates. © 2003 The American Physical Society URL:
