Yang-Rice-Zhang description of checkerboard pattern and autocorrelation of photoemission data in high-temperature superconductors

In the pseudogap state, the spectrum of the autocorrelation of angle resolved photoemission spectroscopy (AC-ARPES) data of Bi2Sr2CaCu2O8+delta presents nondispersive peaks in momentum space, while dispersive peaks are found in the superconducting state. Both dispersive and nondispersive features compare well with those found in Fourier transform scanning tunneling spectroscopy (FT-STS). Here, we show that the experimental AC-ARPES spectrum can be reproduced using the Yang-Rice-Zhang model for the pseudogap with no intrinsic charge ordering or symmetry breaking. This result suggests that quantum interference of quasiparticles can also play a role in the nondispersive features of FT-STS associated with the so-called checkerboard pattern in the pseudogap state. Due to the competition of superconductivity and pseudogap included in this model, we obtain both dispersive and nondispersive peaks in the AC-ARPES data of superconducting underdoped cuprates.
