My group uses atoms to study the nature of physical laws. Our current projects involve

  • looking for physics beyond the Standard Model
  • building new kinds of atomic clocks

Recent work

  2. Development of room-temperature and cryogenic strontium ion clocks EFTS/IFCS Conf. (2023)
  3. Nuclear T-violation search using octupole-deformed nuclei in a crystal Phys. Rev. A (2023)
  4. Optical control of BaF molecules trapped in neon ice New J. Phys. (2023)
