Electron enrichment of zigzag edges of armchair-oriented graphene nano-ribbons increases their stability and induces pinning of Fermi level
E. Louis, E. San-Fabian, G. Chiappe +1
Zigzag edges of neutral armchair-oriented Graphene Nano-Ribbons show states strongly localized at those edges. They behave as free radicals that can capture electrons during proces…

Single-photon exchange interaction in a semiconductor microcavity
G. Chiappe, J. Fernández-Rossier, E. Louis +1
We consider the effective coupling of localized spins in a semiconductor quantum dot embedded in a microcavity. The lowest cavity mode and the quantum dot exciton are coupled and c…

Classical trajectories in quantum transport at the band center of bipartite lattices with or without vacancies
G. Chiappe, E. Louis, M. J. Sanchez +1
Here we report on several anomalies in quantum transport at the band center of a bipartite lattice with vacancies that are surely due to its chiral symmetry, namely: no weak locali…
