Dr. Barrett's research has shifted towards high precision metrology and focusses on the advancement optical atomic clocks. The CQT clock is based on singly-ionized lutetium, which provides three suitable clock transitions within the one atom. Two of these transitions have favourable systematics compared to world-leading clock systems. His group hopes to further clock performance with a multi-ion system to improve clock stability.
