Scientists from the University of Innsbruck, Austria, led by Rudolf Grimm offer new insights into the extremely complex few-body problem. For the first time, the quantum physicists provide evidence of universal four-body states that are closely connected to Efimov states, in an ultracold sample of cesium atoms. The scientists have just published their findings in the journal Physical Review Letters.
