Phase-continuous comparison of three all-optical time scales over 20 days
Dahyeon Lee, Kyungtae Kim, Zoey Z. Hu +11
Optical frequency standards have progressed rapidly over the past two decades, leading to the anticipated redefinition of the SI second by an optical frequency. However, time scale…
Atomic Coherence of 2 minutes and Instability of 1.5E-18 at 1 s in a Wannier-Stark Lattice Clock
Kyungtae Kim, Alexander Aeppli, William Warfield +3
We explore the limits of atomic coherence and measurement precision in a 87Sr optical lattice clock. We perform a detailed characterization of key effects, including lattice Raman…
High-Stability Single-Ion Clock with Systematic Uncertainty
Mason C. Marshall, Daniel A. Rodriguez Castillo, Willa J. Arthur-Dworschack +10
We report a single-ion optical atomic clock with fractional frequency uncertainty of and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{τ/\mathrm{s…
