Cascade of transitions in twisted and non-twisted graphene layers within the van Hove scenario
Dmitry V. Chichinadze, Laura Classen, Yuxuan Wang +1
Motivated by measurements of compressibility and STM spectra in twisted bilayer graphene, we analyze the pattern of symmetry breaking for itinerant fermions near a van Hove singula…
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…
Competition of Density Waves and Superconductivity in Twisted Tungsten Diselenide
Lennart Klebl, Ammon Fischer, Laura Classen +2
Evidence for correlated insulating and superconducting phases around regions of high density of states was reported in the strongly spin-orbit coupled van-der Waals material twiste…
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…
