Anomalous exchange interaction between intrinsic spins in conducting graphene systems
Anomalous exchange interaction between intrinsic spins in conducting graphene systems
We address the nature and possible observable consequences of singular one-electron states that appear when strong defects are introduced in the metallic family of graphene, namely, metallic carbon nanotubes and nanotori. In its simplest form, after creating two defects on the same sublattice, a state may emerge at the Fermi …
