Search for transient variations of the fine structure constant and dark matter using fiber-linked optical atomic clocks
B. M. Roberts, P. Delva, A. Al-Masoudi +51
We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in…
First observation with global network of optical atomic clocks aimed for a dark matter detection
P. Wcisło, P. Ablewski, K. Beloy +19
We report on the first earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the…
Hyperpolarizability and operational magic wavelength in an optical lattice clock
R. C. Brown, N. B. Phillips, K. Beloy +11
Optical clocks benefit from tight atomic confinement enabling extended interrogation times as well as Doppler- and recoil-free operation. However, these benefits come at the cost o…
Ultra-stable optical clock with two cold-atom ensembles
M. Schioppo, R. C. Brown, W. F. McGrew +10
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation…
An atomic clock with room-temperature blackbody Stark uncertainty
K. Beloy, N. Hinkley, N. B. Phillips +7
The Stark shift due to blackbody radiation (BBR) is the key factor limiting the performance of many atomic frequency standards, with the BBR environment inside the clock apparatus…
An atomic clock with instability
N. Hinkley, J. A. Sherman, N. B. Phillips +6
Atomic clocks have been transformational in science and technology, leading to innovations such as global positioning, advanced communications, and tests of fundamental constant va…
