Our main field of research is the investigation of free clusters. We study the nonlinear response of clusters in strong laser fields, optical properties of neutral clusters in ultracold helium droplets and photoelectron electron spectroscopy of mass-selected metal clusters using VUV- free electron laser (FLASH) radiation.

In addition, the project “clusters on surfaces” investigates nano-structures on surfaces and clusters on surfaces.
