Generation of high-purity, low-temperature samples of K for applications in metrology
L. Antoni-Micollier, B. Barrett, L. Chichet +4
We present an all optical technique to prepare a sample of K in a magnetically-insensitive state with 95\% purity while maintaining a temperature of 6 K. This versatile…
Development of compact cold-atom sensors for inertial navigation
B. Battelier, B. Barrett, L. Fouché +7
Inertial sensors based on cold atom interferometry exhibit many interesting features for applications related to inertial navigation, particularly in terms of sensitivity and long-…
Studies of general relativity with quantum sensors
G. Lefevre, G. Condon, I. Riou +15
We present two projects aiming to probe key aspects of the theory of General Relativity with high-precision quantum sensors. These projects use cold-atom interferometry with the ai…
Correlative methods for dual-species quantum tests of the weak equivalence principle
B. Barrett, L. Antoni-Micollier, L. Chichet +5
Matter-wave interferometers utilizing different isotopes or chemical elements intrinsically have different sensitivities, and the analysis tools available until now are insufficien…
