Fluctuation diagnostics of the electron self-energy: Origin of the pseudogap physics
O. Gunnarsson, T. Schäfer, J. P. F. LeBlanc +5
We demonstrate how to identify which physical processes dominate the low-energy spectral functions of correlated electron systems. We obtain an unambiguous classification through a…

Dynamical vertex approximation in its parquet implementation: application to Hubbard nano-rings
A. Valli, T. Schäfer, P. Thunström +5
We have implemented the dynamical vertex approximation (DA) in its full parquet-based version to include spatial correlations on all length scales and in {\sl all} scattering ch…

Fate of the false Mott-Hubbard transition in two dimensions
T. Schäfer, F. Geles, D. Rost +6
We have studied the impact of non-local electronic correlations at all length scales on the Mott-Hubbard metal-insulator transition in the unfrustrated two-dimensional Hubbard mode…
