Abstract The time evolution of laser excited small clusters such as Na 309 is investigated using a classical MD simulation code. Results for the electron phase space distribution are analyzed. We are interested intime dependent density and temperature profiles. The question of local thermal equilibrium is addressed comparing the simulated profiles with predictions from equilibrium statistical physics. Once the local thermal equilibrium is established, the time evolution of collective modes of the excited electron system can be investigated. For this, a restricted MD simulation scheme has been developed (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
