Real-time modelling of Optical orientation in GaAs: generation and decay of the degree of spin polarization
Marco D'Alessandro, Davide Sangalli
We present a real-time abinitio description of optical orientation in bulk GaAs due to the coupling with an ultrashort circular polarized laser source. The injection of spin polari…
Many-body perturbation theory calculations using the yambo code
D. Sangalli, A. Ferretti, H. Miranda +17
yambo is an open source project aimed at studying excited state properties of condensed matter systems from first principles using many-body methods. As input, yambo requires groun…
First-principles approach to excitons in time-resolved and angle-resolved photoemission spectra
E. Perfetto, D. Sangalli, A. Marini +1
We show that any {\em quasi-particle} or GW approximation to the self-energy does not capture excitonic features in time-resolved (TR) photoemission spectroscopy. In this work we p…
Ultra--fast carriers relaxation in bulk silicon following photo--excitation with a short and polarized laser pulse
Davide Sangalli, Andrea Marini
A novel approach based on the merging of the out--of--equilibrium Green's function method with the ab-initio, Density--Functional--Theory is used to describe the ultra--fast carrie…
The role of oxygen vacancies on the structure and the density of states of iron doped zirconia
Davide Sangalli, Alessio Lamperti, Elena Cianci +3
In this paper we study, both with theoretical and experimental approach, the effect of iron doping in zirconia. Combining density functional theory (DFT) simulations with the exper…
Pseudo-potentials based first-principles approach to the magneto-optical Kerr effect: from metals to the inclusion of local fields and excitonic effects
Davide Sangalli, Andrea Marini, Alberto Debernardi
We propose a first-principles scheme for the description of the magneto-optical kerr effect within density functional theory (DFT). Though the computation of Kerr parameters is oft…
