Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…

Real-space cluster dynamical mean-field theory: Center focused extrapolation on the one- and two particle level
Marcel Klett, Nils Wentzell, Thomas Schäfer +4
We revisit the cellular dynamical mean-field theory (CDMFT) for the single band Hubbard model on the square lattice at half filling, reaching real-space cluster sizes of up to 9 x…
