LKB - Trapped Ions Metrology

Trapped Ions Group

The group’s activity is centered on precision measurements with cold trapped ions. In particular, the simplest of all molecules, the H2+ ion, is studied both experimentally and theoretically. The general aim of this research is to test fundamental theories and improve our knowledge of fundamental physical constants.
