Band Structure and Topological Properties of Graphene in a Superlattice Spin Exchange Field
Luis Brey, A. R. Carvalho, H. A. Fertig
We analyze the energy spectrum of graphene in the presence of spin-orbit coupling and a unidirectionally periodic Zeeman field, focusing on the stability and location of Dirac poin…

Edge magnetization and local density of states in chiral nanoribbons
A. R. Carvalho, J. H. Warnes, C. H. Lewenkopf
We study the edge magnetization and the local density of states of chiral graphene nanoribbons using a π-orbital Hubbard model in the mean-field approximation. We show that the inc…
