Cold atom clocks have made remarkable progresses in the last two decades and played critical roles in precision measurements. Primary Cs fountain frequency standards have achieved a total uncertainty of a few parts in 1016, and the best optical clock has reached a type B uncertainty below 10-18...

A high-flux and compact cold-atom source with low power consumption developed by an Oxford University-led research group is poised to enable devices such as space-based atomic clocks, improving quantum applications for communication and navigation. The research is a step toward portable quantum ...
In two-beam experiments a short pumping pulse creates a specific population distribution in the cold-atom sample and probe light is then used to record the time-dependent rotation. To minimize the probe’s influence on atoms, it can be either attenuated, detuned from the optical resonance, and...
cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. Prospective applications include metrology, geodesy and measurement of terrestrial mass change due to, e.g., climate change, and fundamental science experiments such as tests of the ...
Cover design: Amie Fernandez Atomic physics was radically trans- formed by the ability to produce and manipulate cold and ultracold atoms. Achieving ultralow tem- peratures has led to many break- throughs — from realizing long-sought phases of matter to the world's most precise clocks. ...
In the present paper, we study the applications of this kind of cooling scheme on the cold atomic clocks to obtain better frequency stability in the future. In previous studies about atom cooling with OFCs, the cooling processes mainly involved single-photon interactions with the atoms [28,29,...
A route to understanding dark energy—and to better sensors and clocks Bigelow says the scientists plan to run experiments using a two-atom interferometer and quantum gases to measure gravity with high precision to learn about the nature of dark energy, the mysterious driver behind the accelerating...
