Abstract:
We study the excitation of metal clusters irradiated by intense laser beams, within the framework of a time dependent density functional approach at fully quantal or semiclassical levels. We focus on ionization processes and energy deposition. It is shown that intense lasers are as efficient as energetic ions to create highly charged clusters, and with comparable deposited excitation energy. We also discuss coupling of electronic to ionic degrees of freedom. We finally consider the importance of accounting for dynamical two-body correlations in the semiclassical approximation and discuss second harmonic generation.
