Quasi-particle functional Renormalisation Group calculations in the two-dimensional t-t'-Hubbard model
Daniel Rohe
We extend and apply a recently introduced quasi-particle functional renormalisation group scheme to the two-dimensional Hubbard model with next-nearest-neighbour hopping and away f…
Interaction flow method reloaded
Daniel Rohe
A recently proposed extension of the interaction flow method is applied to exemplary cases of selected physical and methodical parameters for the two-dimensional Hubbard model away…
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…
Pseudogap opening in the two-dimensional Hubbard model: A functional renormalization group analysis
Cornelia Hille, Daniel Rohe, Carsten Honerkamp +1
Using the recently introduced multiloop extension of the functional renormalization group, we compute the frequency- and momentum-dependent self-energy of the two-dimensional Hubba…
High-performance functional renormalization group calculations for interacting fermions
J. Lichtenstein, D. Sánchez de la Peña, D. Rohe +3
We derive a novel computational scheme for functional Renormalization Group (fRG) calculations for interacting fermions on 2D lattices. The scheme is based on the exchange parametr…
Hierarchical Parallelisation of Functional Renormalisation Group Calculations -- hp-fRG
Daniel Rohe
The functional renormalisation group (fRG) has evolved into a versatile tool in condensed matter theory for studying important aspects of correlated electron systems. Practical app…
