Using interferometers to measure molecular properties — •Philipp Rieser, Armin Shayeghi, and Markus Arndt — University of Vienna, Faculty of Physics, Vienna Center for Quantum Science and Technology (VCQ), , Boltzmanngasse 5, A-1090 Vienna, Austria

The wave nature of molecules is a perfect example of the peculiarities of quantum physics. Molecular quantum optics deals with phenomena related to this wave nature, particularly the interaction of molecules with light.

The working principle of molecule interferometers, namely generating nanoscale fringes in the density distribution of molecular beams, makes them sensitive to external perturbations at nanometre scale. This high sensitivity to beam shifts and dephasing effects can be used to extract a variety of intrinsic molecular electronic properties[1].

Molecular matter-wave experiments have the potential of opening a wide field of research at the interface between quantum optics and chemical physics. Complex many-body systems have a vast variety of electric, magnetic and optical properties that make controlled perturbations an interesting and possibly useful tool for future applications[2].
