Abstract

Laser interaction with a metal excites electrons into a non-equilibrium state after which the path back to equilibrium is determined by the scattering of electrons and phonons. We present a computational study of such a process in a metallic system showing the role of electron-phonon and phonon-phonon coupling. Our modelling approach incorporates realistic momentum resolved electron-phonon coupling in a classical molecular dynamics simulation. In addition, the phonon-phonon scattering is controlled by varying the anharmonicity of the interatomic potential. Our results show that both electron-phonon and phonon-phonon couplings are important in order to match experimental measurements.
