We investigate the geometrical and electronic structure of solids, thin films, and surfaces and their response to the excitation by femtosecond laser pulses. The research topics range from single electron dynamics at ferromagnetic metal and semiconductor surfaces to the collective response of the electronic system to intense laser excitation. Thereby the coupling of electronic excitations to nuclear motion, including vibrations, molecular switching and phase transitions is studied.
