Tests of Fundamental Physics: Spectroscopy

High-precision atomic spectroscopy experiments and theory to probe new physics, dark matter and the variation of constants.

Activities

  • Probing new physics through isotope shift spectroscopy using highly charged ions
  • Working on test theories beyond SME
  • Clock tests in gravitational fields
  • Spectroscopic tests of dark matter and variation of constants
  • Tests of fundamental decoherence
