The problem of electron-electron interactions in graphene is reviewed. Starting from the
screening of long-range interactions in these systems, the existence of an emerging Dirac …

Spintronics holds the promise for future information technologies. Devices based on
manipulation of spin are most likely to replace the current silicon complementary metal …

Single-or few-layer phosphorene is a novel two-dimensional direct-bandgap nanomaterial.
Based on first-principles calculations, we present a systematic study on the binding energy …

Graphene, a single atomic layer of graphite, has been the focus of recent intensive studies
due to its novel electronic and structural properties. Metals grown on graphene also have …

We address the interaction of graphene with 3 d transition-metal adatoms and the formation
of localized magnetic moments by means of first-principles calculations. By comparing …

This article summarizes our understanding of the Kondo effect in graphene, primarily from a
theoretical perspective. We shall describe different ways to create magnetic moments in …

In this work, the lattice structure of bilayer graphene armchair nanoribbons atoms within the
same layer are studied by Monte Carlo simulations. The ground state phase diagrams of …

We study spin excitations and the Kondo effect in open-shell nanographenes, motivated by
recent scanning tunneling inelastic spectroscopy experiments. Specifically, we consider …

The Kondo effect, a widely studied phenomenon in which the scattering of conduction
electrons by magnetic impurities increases as the temperature T is lowered, depends …

We determine the magnetic properties of individual Co atoms adsorbed on graphene (G)
with x-ray absorption spectroscopy and magnetic circular dichroism. The magnetic ground …
