Putting a new theory of many-particle quantum systems to the test - "Quantum many-body systems—which are composed of many interacting particles, such as atoms—are at the heart of atomic, nuclear, and particle "Our measurements matched the prediction of theory across dozens of trap oscillations," said Weiss. "There currently aren't other ways to
