Dynamical Cluster Approximation

The dynamical cluster approximation (DCA) is a method which systematically incorporates nonlocal corrections to the dynamical mean-field approximation. Here we present a pedagogical discussion of the DCA by describing it as a ̊-derivable coarse-graining approximation in k-space, which maps an infinite lattice problem onto a periodic finite-sized cluster embedded in a self-consistently determine...

Electronic structure of SrVO3„001... surfaces: A local-density approximation plus dynamical mean-field theory calculation

The influence of local Coulomb correlations on the surface electronic structure of SrVO3, a stronglycorrelated metal in a perovskite structure, is investigated for both the SrO-layer and VO2-layer-terminated 001 surfaces. The electronic structure within the local density approximation of a semi-infinite surface is determined using the embedded Green-function approach, and the resultant density ...
