When a two-body relation becomes a three-body relation, the
behaviour of the system changes and typically becomes more complex. While the
basic physics of two interacting particles is well understood, the mathematical
description of a three- or many-body system becomes increasingly difficult,
such that calculating the dynamics can blast the capacities of even modern
super computers. However, under certain conditions, the quantum mechanical
three-body problem may have a universal scaling solution. The predictions of
such a model have now been confirmed experimentally by physicists of Heidelberg
University. The scientists under Prof. Dr. Matthias Weidemüller investigated
three-particle molecules, known as trimers, under exotic conditions
