abstract

We investigate the effect of the Continuous Spontaneous Localization (CSL) model on light-pulse atom interferometry. Using a path-integral approach with an additional stochastic potential accounting for CSL, we derive an exponential loss of the contrast that scales linearly with the interferometer time $T$ if both interferometer arms are spatially separated. We compare our theoretical results with measurements from a cold rubidium atom interferometer based on counter-propagating two-photon transitions with pulse separation times up to $T$ = 260 ms and obtain the corresponding bounds on the CSL parameters.

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Long-baseline atom interferometers could detect ultra-light spin-2 dark matter through three coupling channels, reaching mass and coupling ranges that LIGO and LISA cannot cover.
