Functional renormalization of spinless triangular-lattice fermions: -patch vs. truncated-unity scheme
Nico Gneist, Dominik Kiese, Ravn Henkel +3
We study competing orders of spinless fermions in the triangular-lattice Hubbard model with nearest-neighbor interaction. We calculate the effective, momentum-resolved two-particle…
Competing instabilities of the extended Hubbard model on the triangular lattice: Truncated-unity functional renormalization group and application to moiré materials
Nico Gneist, Laura Classen, Michael M. Scherer
A simple yet paradigmatic model for the interplay of strong electronic correlations and geometric frustration is the triangular lattice Hubbard model. Recently it was proposed that…
Cluster functional renormalization group and absence of a bilinear spin liquid in the --Heisenberg model
Dietrich Roscher, Nico Gneist, Michael M. Scherer +2
The pseudofermion functional renormalization group (pf-FRG) has been put forward as a semi-analytical scheme that, for a given microscopic spin model, allows to discriminate whethe…
