From infinite to two dimensions through the functional renormalization group
C. Taranto, S. Andergassen, J. Bauer +5
We present a novel scheme for an unbiased and non-perturbative treatment of strongly correlated fermions. The proposed approach combines two of the most successful many-body method…
Divergent Precursors of the Mott-Hubbard Transition at the Two-Particle Level
T. Schäfer, G. Rohringer, O. Gunnarsson +3
Identifying the fingerprints of the Mott-Hubbard metal-insulator transition may be quite elusive in correlated metallic systems if the analysis is limited to the single particle le…
One-particle irreducible functional approach - a new route to diagrammatic extensions of DMFT
G. Rohringer, A. Toschi, H. Hafermann +3
We present an approach which is based on the one-particle irreducible (1PI) generating functional formalism and includes electronic correlations on all length-scales beyond the loc…
