Surface based detection schemes for molecular interferometry experiments - implications and possible applications — •Adriana Milic, Thomas Juffmann, Michael Müllneritsch, and Markus Arndt — University of Vienna, Faculty of Physics

Surface-based detection schemes for molecular interferometry experiments might be crucial for the search of quantum properties of larger becoming objects, since they provide single particle sensitivity. Here we report on molecular interferograms of different biomolecules imaged using fluorescence microscopy. Being able to watch the build-up of an interferogram live and in situ reveals the matter-wave behavior of these complex molecules in an unprecedented way. We encounter several problems due to van-der-Waals forces between the molecules and the diffraction grating and discuss possible ways to circumvent these. Especially, the advent of 1-100 atomic layers thin diffraction masks might path the way towards molecular holography. We also discuss other possible applications such as coherent molecular microscopy.
