Precision measurements of gravity using cold atom sensors [PDF]

Journal of the European Optical Society-Rapid Publications, 2009
We present a synthetic view of experiments we are performing using atom interferometry to determine the gravitational constant G and to test the Newtonian gravitational law at micrometric distances.

Circulating pulse cavity enhancement as a method for extreme momentum transfer atom interferometry

Communications Physics, 2021
Atom interferometry using single photon transitions has the potential to provide new tools for fundamental physics. This work proposes a circulating pulse scheme for enabling atom interferometry to operate in optical cavities without being constrained in

Light-pulse atom interferometry with entangled atom-optical elements

Physical Review Research, 2022
The analogs of optical elements in light-pulse atom interferometers are generated from the interaction of matter waves with light fields. As such, these fields possess quantum properties, which fundamentally lead to a reduced visibility in the observed ...

Decoherence Spectroscopy for Atom Interferometry

Atoms, 2016
Decoherence due to photon scattering in an atom interferometer was studied as a function of laser frequency near an atomic resonance. The resulting decoherence (contrast-loss) spectra will be used to calibrate measurements of tune-out wavelengths that ...
