Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

We review experimental progress on optical atomic clocks and frequency transfer, and
consider the prospects of using these technologies for geodetic measurements. Today …

We report an optical lattice clock with a total systematic uncertainty of 8.1× 10-19 in fractional
frequency units, representing the lowest uncertainty of any clock to date. The clock relies on …

We report on an improved systematic evaluation of the JILA SrI optical lattice clock,
achieving a nearly identical uncertainty compared to the previous strontium record set by the …

Optical atomic clocks, due to their unprecedented stability,–and uncertainty,,–, are already
being used to test physical theories, and herald a revision of the International System of …

The pursuit of better atomic clocks has advanced many research areas, providing better
quantum state control, new insights in quantum science, tighter limits on fundamental …

Progress in atomic, optical and quantum science, has led to rapid improvements in atomic
clocks. At the same time, atomic clock research has helped to advance the frontiers of …

We demonstrate single-shot imaging and narrow-line cooling of individual alkaline-earth
atoms in optical tweezers; specifically, strontium trapped in 515.2-nm light. Our approach …

The accuracy of atomic clocks relies on the superb reproducibility of atomic spectroscopy,
which is accomplished by careful control and the elimination of environmental perturbations …

SU (N) symmetry can emerge in a quantum system with N single-particle spin states when
spin is decoupled from interparticle interactions. Taking advantage of the high measurement …
