Matter wave interferometry: Molecular mass, complexity, dynamics and structure — •Sandra Eibenberger1, Stefan Gerlich1, Jens Tüxen2, Stefan Nimmrichter1, Marcel Mayor2, and Markus Arndt1 — 1University of Vienna, Quantum Nanophysics, Austria — 2University of Basel, Department of Chemistry, Switzerland
Kapitza-Dirac-Talbot-Lau interferometry is a versatile tool for studying the wave nature of massive and complex molecules.
De Broglie coherence is to first order only associated with the center-of-mass motion. In the presence of external perturbations, however, internal molecular properties, such as electric susceptibilities, polarizabilities or dipole moments become accessible without introducing genuine decoherence.
Recent experimental data from high-contrast interference measurements with massive and complex molecules are presented. The influence of molecular dynamics on de Broglie coherence and the distinction of structural isomers via quantum metrology are shown.
