Complex oscillations in a quantum system simplify with time

With a sophisticated experiment, physicists have shown that in a one-dimensional quantum system, the initially complex distribution of oscillations or phonons can change into a simple Gaussian bell curve over time. A joint research group of the Freie Universität Berlin and the HZB, led by professor Jens Eisert, developed theoretical foundations for an experiment that was carried out at the Vienna University of Technology.

Determining the nature of quantum resonances by probing elastic and reactive scattering in cold collisions

Scientists from Freie Universität Berlin, Israel's Weizmann Institute of Science, and the Netherlands' Radboud University have demonstrated two types of quantum resonances: tunneling resonances and above-barrier resonances. The team of physicists and chemists combined the merged-beam technique with VMI detection assisted by near-threshold photoionization to resolve the resonances and corroborated their findings by calculating the corresponding scattering wavefunctions.
