Real-space dynamical mean-field theory of Friedel oscillations in strongly correlated electron systems
B. Chatterjee, J. Skolimowski, K. Makuch +1
We study Friedel oscillations and screening effects of the impurity potential in the Hubbard model. Electronic correlations are accounted for by solving the real-space dynamical me…

T-matrix formulation of real-space dynamical mean-field theory and the Friedel sum rule for correlated lattice fermions
K. Byczuk, B. Chatterjee, D. Vollhardt
We formulate real-space dynamical mean-field theory within scattering theory. Thereby the Friedel sum rule is derived for interacting lattice fermions at zero temperature.
