Scientists discover atoms suddenly spinning backward in quantum experiment

An international team of researchers has directly observed how angular momentum moves through a crystal lattice for the first time, revealing an unexpected quantum effect that causes the direction of rotation to reverse. The discovery, made using intense terahertz laser pulses, gives scientists a new view into the fundamental origins of magnetism and could eventually help researchers better control advanced quantum materials.
