Expérimental
The aim of this intership is the implementation of the "Delta-Kick squeezing" (DKS) technique, recently proposed. This DKS rely on the engineering of atom atom interactions in a BEC in free fall. Such interactions induce strong correlations between the atoms, and lead to squeezing in the population difference between the two interferometer paths, and is thus a promising route we want to explore for reaching phase sensitivity below the standard quantum limit.
