Atom Interferometry with Transverse Optical Modes
Ryan Husband, Ryan J. Thomas, Yosri Ben-Aïcha +10
We experimentally demonstrate atom interferometry using the transverse phase profile of an optical mode. As proof-of-principle, we use the helical phase windings of Hypergeometric…

Tensor gravity gradiometry with a single-axis atom gradiometer
Ryan J. Thomas, Samuel Legge, John D. Close
We propose a method for using a single-axis atom interferometric gravity gradiometer to measure off-diagonal elements of the gravity gradient tensor. By tilting the gradiometer, th…

Multimode feedback cooling of the collective modes of a Bose-Einstein condensate
Ryan J. Thomas, Jordan A. McMahon, Zain Mehdi +5
We experimentally demonstrate cavity-free feedback cooling of the three lowest-lying collective modes of a Bose-Einstein condensate in a prolate harmonic trap. Using shadowgraph im…
