The Economics of the DeLend Project: Agent-based Simulations
Frederico Dutilh Novaes, Gabriel de Abreu Madeira, Aurimar Cerqueira
This paper presents our methodology to simulate the behavior of the DeLend Platform. Such simulations are important to verify if the system is able to connect the different sets of…
Elastic transport through dangling-bond silicon wires on H passivated Si(100)
Mikaël Kepenekian, Frederico D. Novaes, Roberto Robles +4
We evaluate the electron transmission through a dangling-bond wire on Si(100)-H (2x1). Finite wires are modelled by decoupling semi-infinite Si electrodes from the dangling-bond wi…
Excitation of local magnetic moments by tunnelling electrons
Jean-Pierre Gauyacq, Nicolas Lorente, Frederico Dutilh Novaes
The advent of milli-kelvin scanning tunneling microscopes (STM) with inbuilt magnetic fields has opened access to the study of magnetic phenomena with atomic resolution at surfaces…
Negative differential resistance in scanning tunneling microscopy: simulations on C-based molecular overlayers
Frederico D. Novaes, Manuel Cobian, Alberto Garcia +3
We determine the conditions in which negative differential resistance (NDR) appears in the C-based molecular device of [Phys. Rev. Lett. {\bf 100}, 036807 (2008)] by means o…
Quenching of magnetic excitations in single adsorbates at surfaces: Mn on CuN/Cu(100)
Frederico D. Novaes, Nicolás Lorente, Jean-Pierre Gauyacq
The lifetimes of spin excitations of Mn adsorbates on CuN/Cu(100) are computed from first-principles. The theory is based on a strong-coupling T-matrix approach that evaluates the…
Magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine molecules (M Fe, Co)
Jean-Pierre Gauyacq, Frederico D. Novaes, Nicolás Lorente
We report on a theoretical study of magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine (M-Pc) molecules where M is a metal atom: Fe-Pc on…
Oxygen clamps in gold nanowires
Frederico D. Novaes, Antonio J. R. da Silva, E. Z. da Silva +1
We investigate how the insertion of an oxygen atom in an atomically thin gold nanowire can affect its rupture. We find, using ab initio total energy density functional theory calcu…
