Equilibrium and out-of-equilibrium over-screening free phonon self-energy in realistic materials
Andrea Marini
In model Hamiltonians, like Fröhlich's, the electron-phonon interaction is assumed to be screened from the beginning. The same occurs when this interaction is obtained by using the…
Exciton-phonon interaction calls for a revision of the "exciton" concept
Fulvio Paleari, Andrea Marini
The concept of \textit{optical} exciton - a photo-excited bound electron-hole pair within a crystal - is routinely used to interpret and model a wealth of excited-state phenomena i…
Ultrafast Charge Migration in XUV Photoexcited Phenylalanine: a First-Principles Study Based on Real-Time Nonequilibrium Green's Functions
E. Perfetto, D. Sangalli, A. Marini +1
The early stage density oscillations of the electronic charge in molecules irradiated by an attosecond XUV pulse takes place on femto- or subfemtosecond timescales. This ultrafast…
Electron-phonon scattering effects on electronic and optical properties of orthorhombic GeS
Cesar E. P. Villegas, A. R. Rocha, A. Marini
Group-VI monochalcogenides are attracting a great deal of attention due to their peculiar anisotropic properties. Very recently, it has been suggested that GeS could act as a promi…
Temperature dependence of the electronic structure of semiconductors and insulators
Samuel Poncé, Yannick Gillet, Jonathan Laflamme Janssen +3
The renormalization of electronic eigenenergies due to electron-phonon coupling is sizable in many materials with light atoms. This effect, often neglected in ab-initio calculation…
Complete collisions approximation to the Kadanoff-Baym equation: a first--principles implementation
D. Sangalli, A. Marini
We show carriers dynamics on bulk Silicon in the sub pico-second time scale. The results are obtained from a first-principles implementation of the the Kadanoff-Baym equations with…
