Femtosecond dynamics of electrons and photons in metal nanostructures: recent progress
We review recent progress in modelling and experiments of the femtosecond dynamics of the non-equilibrium energy distribution of electrons in metals following a femtosecond pulse. In particular, we describe an improved modelling approach, and correlated measurements of the spatio-temporal dynamics of the metal permittivity; we also identify the different signature that this dynamics has on the contribution of interband and intraband transitions on the dynamics of the metal permittivity. We then study the effect of chirp on these properties, and discuss insights from photon and electron emission experiments.
