KRb: Solving Hard Quantum Problems: Everything is Connected

threeBECscollisionCyan
Quantum objects cannot just be understood as the sum of their parts. This is what makes quantum calculations so complicated. Scientists at TU Wien (Vienna) have now calculated Bose-Einstein-condensates, revealing the secrets of the particles’ collective behaviour.
