Atom Interferometry with Floquet Atom Optics

open access: yesPhysical Review Letters, 2022
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement a periodic atom-light coupling to realize Floquet atom optics on the strontium ${}^1\!S_0\,\text{-}\, {}^3\!P_1$ transition.
