Induced Nonlinear Interactions and Parameter Estimation in Cold Atoms

Heather Partner, University of New Mexico

(Session 5 : Friday from 5:00-7:00)

Abstract. Recent progress in both theory and experiment have suggested that nonlinear interactions could provide improved uncertainty scaling for quantum precision measurements. It is our goal to translate these ideas into a functional experimental design, specifically in atomic magnetometry. We discuss our plans to perform double-passed continuous measurements on the collective spin of cooled atoms in a fountain configuration, with the aim of investigating improvements over single-pass geometries.
