Exact diagonalization study of the tunable edge magnetism in graphene
David J. Luitz, Fakher F. Assaad, Manuel J. Schmidt
The tunable magnetism at graphene edges with lengths of up to 48 unit cells is analyzed by an exact diagonalization technique. For this we use a generalized interacting one-dimensi…
Dynamic charge correlations near the Peierls transition
Martin Hohenadler, Holger Fehske, Fakher F. Assaad
The quantum phase transition between a repulsive Luttinger liquid and an insulating Peierls state is studied in the framework of the one-dimensional spinless Holstein model. We foc…
Dynamical Signatures of Edge-State Magnetism on Graphene Nanoribbons
Hélène Feldner, Zi Yang Meng, Thomas C. Lang +3
We investigate the edge-state magnetism of graphene nanoribbons using projective quantum Monte Carlo simulations and a self-consistent mean-field approximation of the Hubbard model…
