University of Innsbruck The team of Francesca Ferlaino, Institute for Experimental Physics of the University of Innsbruck, Austria, has experimentally shown chaotic behavior of particles in a quantum gas. "For the first time we have been able to observe quantum chaos in the scattering behavior of ultracold atoms," says an excited Ferlaino. The physicists used random matrix theory to confirm their results, thus asserting the universal character of this statistical theory. Nobel laureate...

Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics. Even tiny, easily overlooked events can completely change the behavior of a complex system, to the point where there is no apparent order to most natural systems we deal with in everyday life. The weather is one familiar case, but other well-studied examples can be found in chemical reactions, population dynamics, neural networks and even the...

In the macroscopic world of everyday life we often have 'deterministic chaos'. Events like weather and ocean currents, the movement of heavenly bodies, or the growth of insect populations can all be described in exact formulas. They are indeed 'deterministic'. But the way they proceed in reality is highly sensitive to initial values. Even the smallest failure to measure the initial conditions can make a long-term prediction impossible. Physicists call such systems 'chaotic'. Microscopic...
