Self-energy feedback and frequency-dependent interactions in the functional renormalization group flow for the two-dimensional Hubbard model
Stefan Uebelacker, Carsten Honerkamp
We study the impact of including the self-energy feedback and frequency-dependent interactions on functional renormalization group grows for the two-dimensional Hubbard model on th…
Interacting electrons on trilayer honeycomb lattices
Michael M. Scherer, Stefan Uebelacker, Daniel D. Scherer +1
Few-layer graphene systems come in various stacking orders. Considering tight-binding models for electrons on stacked honeycomb layers, this gives rise to a variety of low-energy b…
Antiferromagnetism in the Hubbard Model on the Bernal-stacked Honeycomb Bilayer
Thomas C. Lang, Zi Yang Meng, Michael M. Scherer +5
Using a combination of quantum Monte Carlo simulations, functional renormalization group calculations and mean-field theory, we study the Hubbard model on the Bernal-stacked honeyc…
Instabilities of interacting electrons on the honeycomb bilayer
Michael M. Scherer, Stefan Uebelacker, Carsten Honerkamp
We investigate the instabilities of interacting electrons on the honeycomb bilayer by means of the functional renormalization group for a range of interactions up to the third-near…
Multiband Effects on Superconducting Instabilities Driven by Electron-Electron Interactions
Stefan Uebelacker, Carsten Honerkamp
We explore multiband effects on d-wave superconducting instabilities driven by electron-electron interactions. Our models on the two-dimensional square lattice consist of a main ba…
Instabilities of quadratic band crossing points
Stefan Uebelacker, Carsten Honerkamp
Using a functional renormalization group approach, we study interaction-driven instabilities in quadratic band crossing point two-orbital models in two dimensions, extending a prev…
