Spin selectivity in angle-resolved Auger photoelectron coincidence spectroscopy (AR-APECS) is used to probe electron correlation in ferromagnetic thin films. In particular, exploiting the AR-APECS capability to discriminate Auger electron emission ev

The line shape of the Auger decay of adatoms is studied by a joint theoretical and experimental effort, the former within a DFT framework, and the latter with synchrotron radiation measurements. We investigate the $K{L}_{2,3}V$ Auger deexcitation of

Ab initio calculation of core-valence-valence Auger spectra in closed shell systems

Autor: G. P. Brivio, Michele Cini, M. I. Trioni, S Ugenti, Enrico Perfetto, G. Fratesi

We propose an ab initio method to evaluate the core-valence-valence (CVV) Auger spectrum of systems with filled valence bands. The method is based on the Cini-Sawatzky theory, and aims at estimating the parameters by first-principles calculations in

Quantum suppression of chaotic diffusion: Theory and experiment

Autor: Luca Perotti, G. P. Brivio, Italo Guarneri, Giulio Casati

Publikováno v: Physica D: Nonlinear Phenomena. 33:51-57

In this paper the question whether any limitation of chaos may be expected when considering a highly excited hydrogen atom in an external microwave field is addressed. Comparison between classical and quantum analytical and numerical results is prese

The gettering theory approach to reactive scattering on surfaces

Autor: T. B. Grimley, G. P. Brivio

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 5:577-580

The quantum theory of gettering (the removal of a gas from a closed vessel by adsorbing it on a solid) has been used to compute sticking coefficients of H and D, with energies in the range 0–80 meV, on a model metal with energy loss to electron‐h
