17 Aug 2022 | | Abstract: | Interferometry is a prime technique for modern precision measurements. Atoms,
unlike light, have significant interactions with electric, magnetic, and
gravitational fields, making their use in interferometric applications
particularly versatile. Here, we demonstrate atom interferometry to image
optical and magnetic potential landscapes over an area exceeding $240 mu m
imes 600 mu m$. The differential potentials employed in our experiments
generate phase imprints in an atom laser that are made visible through a Ramsey
pulse sequence. We further demonstrate how advanced pulse sequences can enhance
desired imaging features, e.g. to image steep potential gradients. A
theoretical discussion is presented that provides a semiclassical analysis and
matching numerics. | | Source: | arXiv, 2208.08007 | | Services: | Forum | Review | PDF | Favorites | |
