Free-carrier-induced nonlinear dynamics in hybrid graphene-based photonic waveguides
Ambaresh Sahoo, Andrea Marini, Samudra Roy
We develop from first principles a theoretical model for infrared pulse propagation in graphene-covered hybrid waveguides. We model electron dynamics in graphene by Bloch equations…
Coherence and de-coherence in the Time-Resolved ARPES of realistic materials: an ab-initio perspective
Andrea Marini, Enrico Perfetto, Gianluca Stefanucci
Coherence and de-coherence are the most fundamental steps that follow the initial photo-excitation occurring in typical Pump&Probe experiments. Indeed, the initial external laser p…
Electron--phonon interaction without overscreening: a strategy for first--principles modelling
Fulvio Paleari, Andrea Marini
State-of-the-art approaches to calculate the electron-phonon and the phonon-electron self-energy are based on a mean-field approximation for the interacting electronic system. This…
Overscreening-free electron-phonon interaction in realistic materials
Fulvio Paleari, Andrea Marini
State-of-the-art model Hamiltonians, like Fröhlich's, or density functional theory approaches to electron-phonon interaction suffer from a severe overscreening error. This is due t…
Non-linear self-driven spectral tuning of Extreme Ultraviolet Femtosecond Pulses in monoatomic materials
Carino Ferrante, Emiliano Principi, Andrea Marini +9
Self-action nonlinearity is a key aspect -- either as a foundational element or a detrimental factor -- of several optical spectroscopies and photonic devices. Supercontinuum gener…
Spinorial formulation of the GW-BSE equations and spin properties of excitons in 2D Transition Metal Dichalcogenides
Margherita Marsili, Alejandro Molina-Sánchez, Maurizia Palummo +2
In many paradigmatic materials, like Transition Metal Dichalcogenides, the role played by the spin degrees of freedom is as important as the one played by the electron-electron int…
