Explanation for puzzling quantum oscillations has been found

(Institute of Science and Technology Austria) Experiments in a system of 53 trapped atoms, presented in 2017 researchers from Harvard and MIT, revealed completely unexpected periodic oscillations in the dynamics of the interacting atoms. Now, an international team of researchers has solved the mystery of these previously inexplicable oscillations. The theoretical explanation they proposed introduces a concept of a "quantum many-body scar" and is a paradigm shift in the dynamics of many-body quantum systems.
