Nonlocal density interactions in auxiliary-field quantum Monte Carlo simulations: application to the square lattice bilayer and honeycomb lattice
Michael Golor, Stefan Wessel
We consider an efficient scheme to simulate fermionic Hubbard models with nonlocal density-density interactions in two dimensions, based on bond-centered auxiliary-field quantum Mo…
Ground state phase diagram of the half-filled bilayer Hubbard model
Michael Golor, Timo Reckling, Laura Classen +2
Employing a combination of functional renormalization group calculations and projective determinantal quantum Monte Carlo simulations, we examine the Hubbard model on the square la…
Quantum Nature of Edge Magnetism in Graphene
Michael Golor, Stefan Wessel, Manuel J. Schmidt
It is argued that the subtle crossover from decoherence-dominated classical magnetism to fluctuation-dominated quantum magnetism is experimentally accessible in graphene nanoribbon…
Magnetic Correlations in Short and Narrow Graphene Armchair Nanoribbons
Michael Golor, Cornelie Koop, Thomas C. Lang +2
Electronic states at the ends of a narrow armchair nanoribbon give rise to a pair of non-locally entangled spins. We propose two experiments to probe these magnetic states, based o…
Effective models for strong electronic correlations at graphene edges
Manuel J. Schmidt, Michael Golor, Thomas C. Lang +1
We describe a method for deriving effective low-energy theories of electronic interactions at graphene edges. Our method is applicable to general edges of honeycomb lattices (zigza…
Quantum Monte Carlo studies of edge magnetism in chiral graphene nanoribbons
Michael Golor, Thomas C. Lang, Stefan Wessel
We investigate chiral graphene nanoribbons using projective quantum Monte Carlo simulations within the local Hubbard model description and study the effects of electron-electron in…
