Quantum effects: Patterns of interfering massive particles

A new study examines the nature of exchange interactions between identical particles, which only occur at the quantum level. Two-particle interference has been the focus of many studies, specifically in quantum optics with photons. However, interference between two massive, identical particles is not so well understood. Scientists have now uncovered a counterintuitive result whereby particles called bosons do not behave as expected-they are overlapping, and not interfering-due to the combination of interference and so-called exchange interaction. The latter is a quantum mechanical effect that alters their symmetry when identical particles are exchanged.
