Abstract
Recently the structure of the measured local density of states power spectrum of a small area of the Bi2Sr2CaCu2O8 surface has been interpreted in terms of peaks at an “octet” of scattering wave vectors determined assuming weak, noninterfering scattering centers. Using analytical arguments and numerical solutions of the Bogoliubov–de Gennes equations, we discuss how the interference between many impurities in a d-wave superconductor alters this scenario. We propose that the peaks observed in the power spectrum are not the features identified in the simpler analyses, but rather “background” structures which disperse along with the octet vectors. We further consider how our results constrain the form of the actual disorder potential found in this material.
