Conserving approximations in direct perturbation theory: new semianalytical impurity solvers and their application to general lattice problems
Norbert Grewe, Sebastian Schmitt, Torben Jabben +1
For the treatment of interacting electrons in crystal lattices approximations based on the picture of effective sites, coupled in a self-consistent fashion, have proven very useful…
