Abstract:
We develop a many-body description of nonadiabatic dynamics of quasiparticles in surface bands valid on the extreme ultrashort time scale by combining the formalism for calculation of quasiparticle survival probabilities with the selfconsistent treatment of electronic response of the system. Applying this approach to the benchmark Cu(111) surface we assess the behavior and intervals of preasymptotic electron and hole dynamics in surface bands and locate the transition to asymptotic regime of exponential quasiparticle decay characterized by the corrected Fermi golden rule-type of transition rate. The general validity of these findings enables distinguishing the various regimes of ultrafast electron dynamics that may be revealed in time resolved experiments.
