Nonequilibrium Photocarrier and Phonon Dynamics from First Principles: a Unified Treatment of Carrier-Carrier, Carrier-Phonon, and Phonon-Phonon Scattering
Stefano Mocatti, Giovanni Marini, Giulio Volpato +2
We develop a first-principles many-body framework to describe the dynamics of photocarriers and phonons in semiconductors following ultrafast excitation. Our approach incorporates…

Separation between long- and short-range part of the Coulomb interaction in low dimensional systems: implications for the macroscopic screening length and the collective charge excitations
Pierluigi Cudazzo
Collective charge excitations directly probed in electron energy loss and inelastic X rays scattering spectroscopies play a key role in different fields of condensed matter physics…
