STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
Generating 500 mW for laser cooling of strontium atoms by injection locking a high power laser diode
Vladimir Schkolnik, Jason R. Williams, Nan Yu
We report on the generation of 500 mW of spectrally pure laser light at the 460.86 nm transition used for laser cooling of strontium atoms. To this end we inject a high power singl…
Constraining symmetron dark energy using atom interferometry
Sheng-wey Chiow, Nan Yu
Symmetron field is one of the promising candidates of dark energy scalar fields. In all viable candidate field theories, a screening mechanism is implemented to be consistent with…
Searching for stochastic background of ultra-light fields with atomic sensors
Tigran Kalaydzhyan, Nan Yu
We propose a cross-correlation method for the searches of ultra-light fields, in particular, with a space network of atomic sensors. The main motivation of the approach is cancella…
Extracting dark matter signatures from atomic clock stability measurements
Tigran Kalaydzhyan, Nan Yu
We analyze possible effects of the dark matter environment on the atomic clock stability measurements. The dark matter is assumed to exist in a form of waves of ultralight scalar f…
Gravity gradient suppression in spaceborne atomic tests of the equivalence principle
Sheng-wey Chiow, Jason Williams, Nan Yu +1
The gravity gradient is one of the most serious systematic effects in atomic tests of the equivalence principle (EP). While differential acceleration measurements performed with di…
