Matter-wave interferometry with large metal clusters in a free-fall setup — •Eric van den Bosch and Klaus Hornberger — University of Duisburg-Essen, Germany
Matter-wave interferometry can be used to probe fundamental quantum properties on increasingly large scales. Using ionising gratings produced by UV lasers mitigates some of the limitations of material gratings, while also allowing for more versatile setups. We study an optical time-domain ionising matter-wave interferometer (OTIMA) setup [1] in a free-fall tower aimed at masses of up to 107 amu. We treat the influence of gravity and the Coriolis force in three dimensions and discuss possible experimental schemes to counteract the Coriolis effect.
