Molecular dissociation in presence of a catalyst : II. The bond breaking role of the transition from virtual to localized states
(2016)
We address a molecular dissociation mechanism that is known to occur when a H 2 molecule approaches a catalyst with its molecular axis parallel to the surface. It is found that molecular dissociation is a form of quantum ...
Tailoring optical fields emitted by nanometric sources
(2014)
In this work we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system studied consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is ...
Landau-Zener and Rabi oscillations in the spin-dependent conductance
(2014)
We describe the spin-dependent quantum conductance in a wire where a magnetic field is spatially modulated. The changes in direction and intensity of the magnetic field acts as a perturbation that mixes spin projections. ...
