Abstract

We theoretically investigate the performance of atom interferometers based on ultracold atoms and atom chips. Within the framework of the Gross‐Pitaevskii equation, we simulate the splitting and trapping of a condensate. Within the two‐mode model and the multi‐configurational Hartree method for Bosons, we investigate number squeezing and its impact on the interferometer performance. We show that optimized control strategies allow for efficient condensate trapping and number squeezing on short time scales.
