New members in the quantum zoo: developments of molecule interferometry

Prof. Dr. Markus Arndt, Universität Wien

The wave nature of massive particles has been at the heart of quantum physics since it was postulated by Louis de Broglie in 1923 and consolidated in Schrödinger's wave mechanics. We here investigate the experimental and/or fundamental limits of quantum interferometry using massive clusters and large organic molecules. We outline the historical and conceptual basis of such experiments and point to the modern challenges and applications for matter wave experiments with large things. The questions that guide our research shall also guide this talk: What are the present and future limits to the particle mass, size and complexity in quantum interference experiments? How can we exploit the high sensitivity of matter waves to external perturbations to gather information about external forces or molecular properties? How can we transfer the precision of molecule interferometry to the deposition of molecular nanostructures?
