It is argued that the subtle crossover from decoherence-dominated classical magnetism to
fluctuation-dominated quantum magnetism is experimentally accessible in graphene …

We calculate exact zero-temperature real-space properties of a substitutional magnetic
impurity coupled to the edge of a zigzag silicenelike nanoribbon. Using a Lanczos …

We study the electronic structure of finite armchair graphene nanoribbons using density-
functional theory and the Hubbard model, concentrating on the states localized at the zigzag …

The topological phases of graphene with spin-orbit coupling, an exchange field, and a
staggered-sublattice potential determine the properties of the edge states of the zigzag …

Electronic states at the ends of a narrow armchair nanoribbon give rise to a pair of
nonlocally entangled spins. We propose two experiments to probe these magnetic states …

We examine the magnetic correlations in quantum spin models that were derived recently as
effective low-energy theories for electronic correlation effects on the edge states of graphene …

It has been proposed that interactions lead to ferromagnetism on a zigzag edge of a
graphene sheet. While not yet directly studied experimentally, dramatically improving …

The electronic and spintronic properties of the monovacancies in freestanding and
isotopically compressed graphene are investigated using hybrid exchange density …

We study the dynamics of an electron spin in a graphene quantum dot, which is interacting
with a bath of less than ten nuclear spins via the anisotropic hyperfine interaction. Due to …

Friedel oscillations of the graphene-like materials are investigated theoretically for low and
intermediate Fermi energies. Numerical calculations have been performed within the …
