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…
Coulomb interaction and charge neutrality: Pariser, Parr and Pople Hamiltonian versus the Extended Hubbard Hamiltonian
E. San-Fabián, J. A. Vergés, G. Chiappe +1
The Extended Hubbard Hamiltonian used by the Condensed Matter community is nothing but a simplified version of the Pariser, Parr and Pople Hamiltonian, well established in the Quan…
Magnetic molecules created by hydrogenation of Polycyclic Aromatic Hydrocarbons
J. A. Verges, G. Chiappe, E. Louis +2
Present routes to produce magnetic organic-based materials adopt a common strategy: the use of magnetic species (atoms, polyradicals, etc.) as building blocks. We explore an altern…
A Novel Approach to Study Highly Correlated Nanostructures: The Logarithmic Discretization Embedded Cluster Approximation
E. V. Anda, G. Chiappe, C. A. Busser +4
This work proposes a new approach to study transport properties of highly correlated local structures. The method, dubbed the Logarithmic Discretization Embedded Cluster Approximat…
Transport through quantum dots: A combined DMRG and cluster-embedding study
F. Heidrich-Meisner, G. B. Martins, C. A. Busser +5
The numerical analysis of strongly interacting nanostructures requires powerful techniques. Recently developed methods, such as the time-dependent density matrix renormalization gr…
Transport regimes in surface disordered graphene sheets
E. Louis, J. A. Verges, F. Guinea +1
We investigate the size scaling of the conductance of surface disordered graphene sheets of width W and length L. Metallic leads are attached to the sample ends across its width. A…
