The de Broglie Wave Nature of Molecules, Clusters and Nanoparticles

WithStefan Gerlich, Stefan Kuhn, Armin Shayeghi, Markus Arndt

For many decades, nanoscience has studied material properties at length scales where quantum effects can dominate mechanical, thermal, optical, magnetic or electronic properties compared to their macroscopic values. Here we focus on the center-of-mass motion, which can also display quantum behavior when particles are sufficiently small and isolated from their environment. The matter-wave nature of complex composite systems can shed light on the foundations of physics while enabling new measurements of internal characteristics of nanoscale systems.
