Electronic structure and magnetism in UGa2: DFT+DMFT approach
Banhi Chatterjee, Jindrich Kolorenc
The debate whether uranium 5f electrons are closer to being localized or itinerant in the ferromagnetic compound UGa2 is not yet fully settled. The experimentally determined magnet…

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.
