Ultracold quantum particles break classical symmetry
(PHYSorg.com Physics)

Many phenomena of the natural world evidence symmetries in their dynamic evolution which help researchers to better understand a system`s inner mechanism. In quantum physics, however, these symmetries are not always achieved. In laboratory experiments with ultracold lithium atoms, researchers from the Center for Quantum Dynamics at Heidelberg University have proven for the first time the theoretically predicted deviation from classical symmetry. Their results were published in the journal Science.
