Experiments with ultra-cold atoms at the TU Wien have shown surprising results: coupled atom clouds synchronize within milliseconds. This effect cannot be explained by standard theories. When atoms are cooled down to almost zero temperature, their properties change completely. They can turn into a Bose-Einstein-Condensate, an ultra-cold state of matter, in which the particles lose their individuality and can only be described collectively - as one single quantum object. At TU Wien (Vienna), clouds of ultra-cold atoms have been studied for years. They are a perfect model system to study fundamental questions of many-particle quantum physics. Now the research team of Professor Jörg Schmiedmayer (Institute of Atomic and Subatomic Physics, TU Wien) has found remarkable results which cannot be explained by any of the existing theories.
