Alexander Aeppli, Willa Arthur-Dworschack, Kyle Beloy, Caitlin Berry, Tobias Bothwell, Angela Folz, Tara Fortier, Tanner Grogan, Youssef Hassan, Zoey Zimeng Hu, David Hume, Benjamin Hunt, Kyungtae Kim, Amanda Koepke, Dahyeon Lee, David Ray Leibrandt, Ben Lewis, Andrew Ludlow, Mason Marshall, Nicholas Nardelli, Harikesh Ranganath, Daniel Rodriguez Castillo, Jeffrey Sherman, Jacob Siegel, Suzanne Thornton, William Warfield, Jun Ye
We report high-precision frequency ratio measurements between optical atomic clocks based on 27Al+, 171Yb, and 87Sr. With total fractional uncertainties at or below 3.2 × 10−18, these measurements meet the milestone criteria for redefinition of the second

Cryogenic photonic resonator with 10-17/s drift

Wei Zhang, William Milner, Jun Ye, Scott Papp
Thermal noise is the predominant instability in the provision of ultrastable laser frequency by reference to a cavity. Reducing the thermal-noise limit of a cavity means either making it larger to spread thermal fluctuations, reducing the sensitivity of

Optical Atomic Clock aboard an Earth-orbiting Space Station (OACESS): Enhancing searches for physics beyond the standard model in space

Vladimir Schkolnik, Dmitry Budker, Oliver Farttman, Victor Flambaum, Leo Hollberg, Tigran Kalaydzhyan, Shimon Kolkowitz, Markus Krutzik, Andrew Ludlow, Nathan R. Newbury, Christopher Pyrlik, Laura Sinclair, Yevgeny Stadnik, Ingmari Tietje, Jun Ye, Jason Williams
We present a concept for a high-precision optical atomic clock (OAC) operating on an Earth-orbiting space station. This pathfinder science mission will compare the space-based OAC with one or more ultra-stable terrestrial OACs to search for space-time

Pauli blocking of atom-light scattering

November 18, 2021

Christian Sanner, Lindsay Sonderhouse, Ross Hutson, Lingfeng Yan, William Milner, Jun Ye
Transition rates between coupled states in a quantum system depend on the density of available final states. The radiative decay of an excited atomic state has been suppressed by reducing the density of electromagnetic vacuum modes near the atomic
