Measurement of a Li tune-out wavelength by phase-patterned atom interferometry
Eric Copenhaver, Kayleigh Cassella, Robert Berghaus +1
Atom interferometers typically use the total populations the interferometer's output ports as the signal, but finer spatial structure can contain useful information. We pattern a m…

Recoil-sensitive lithium interferometer without a subrecoil sample
Kayleigh Cassella, Eric Copenhaver, Brian Estey +3
We report simultaneous conjugate Ramsey-Bordé interferometers with a sample of low-mass (lithium-7) atoms at 50 times the recoil temperature. We optically pump the atoms to a magne…
