Impurities and other defects in correlated lattice electrons: Friedel oscillations and interference patterns
Original language description
We study interference patterns and Friedel oscillations (FO) due to scattering off from two and more localized impurities and scattering off from extended inhomogeneities in the two-dimensional lattice systems of interacting fermions. Correlations between particles are accounted for by using an approximate method based on the real-space dynamical mean-field theory and a homogeneous self-energy approximation where the site-dependent part of the self-energy is neglected. We find that the interference maxima and minima change systematically as we vary the relative distance between the two impurities and the interaction does not shift the position of interference fringes but only reduces their intensities. FO and interference patterns are not present in the Mott insulating phase both in single and many impurity models.
