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…
