Frequency stability of in a Si cavity with AlGaAs crystalline mirrors
Dahyeon Lee, Zoey Z. Hu, Ben Lewis +8
Developments in ultrastable lasers have fueled remarkable advances in optical frequency metrology and quantum science. A key ingredient in further improving laser frequency stabili…
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…
Radio Frequency from Optical with Instabilities below - Generation and Measurement
A. Hati, M. Pomponio, N. V. Nardelli +7
This paper presents a frequency synthesis that achieves exceptional stability by transferring optical signals to the radio frequency (RF) domain at 100 MHz. We describe and charact…
A symmetry-protected topological optical lattice clock
Tianrui Xu, Anjun Chu, Kyungtae Kim +4
We theoretically propose a tunable implementation of symmetry-protected topological phases in a synthetic superlattice, taking advantage of the long coherence time and exquisite sp…
A High-Power Clock Laser Spectrally Tailored for High-Fidelity Quantum State Engineering
Lingfeng Yan, Stefan Lannig, William R. Milner +5
Highly frequency-stable lasers are a ubiquitous tool for optical frequency metrology, precision interferometry, and quantum information science. While making a universally applicab…
