Coexisting magnetic, charge, and superconducting orders in the two-dimensional Hubbard model
Robin Scholle, Pietro M. Bonetti, Walter Metzner +1
We perform a renormalized mean-field study of the two-dimensional repulsive Hubbard model, focusing on the intricate interplay and possible coexistence of magnetic, charge, and sup…

Mean-field analysis of a Hubbard interaction on Bernal Bilayer Graphene
Robin Scholle, Laura Classen
We perform unrestricted Hartree-Fock calculations on the 2D Hubbard model on a honeycomb and bilayer honeycomb lattice at both zero and finite temperatures. Finite size real space…

Spiral to stripe transition in the two-dimensional Hubbard model
Robin Scholle, Walter Metzner, Demetrio Vilardi +1
We obtain an almost complete understanding of the mean-field phase diagram of the two-dimensional Hubbard model on a square lattice with a sizable next-nearest neighbor hopping and…
