One of our lines of research focuses on the properties of metallic clusters, Mn, where M is a metal atom and n ranges from 2 up to ~104. Some ongoing and recent projects:

  • Strong pairing of electrons in nanoclusters with shell structure
    See news story: “Warming up the world of superconductors”
  • Ionization of nanoparticles and its temperature dependence
  • Cluster evaporation
  • Electron-cluster collisions and capture
  • Giant optical resonances due to collective electron oscillations
  • Electric polarizabilities
  • Long-range polarization forces

Cluster beam apparatus

A beam of cluster particles is generated and flies through a series of vacuum chambers. While in flight, the clusters are subjected to various probes. Finally they pass through a mass spectrometer, which can be set to focus on a particular particle mass or to scan through a range of masses.
