Precision metrology and interferometry with ultracold calcium atoms

Abstract

Advances in laser cooling of alkaline earth atoms have reduced trapped atom temperatures from the millikelvin to the microkelvin regime. Using such atoms, our optical atomic clock should have a fractional frequency uncertainty approaching 1×10−15. Sub-recoil cooling and two-pulse atom interferometry are also discussed.
