Researchers Unveil New Insights into Angular Momentum in Quantum Materials
An international team of researchers has made a groundbreaking discovery in the field of quantum materials, observing for the first time how angular momentum is transferred and conserved within a crystal lattice. Using intense terahertz laser pulses, the team was able to control these processes, revealing that during angular momentum transfer, the direction of rotation reverses due to the rotational symmetry of the material. This study, published in Nature Physics, provides new insights into the foundation of magnetism and opens possibilities for tailored control of quantum materials. The research highlights the role of angular momentum at the quantum level, which is crucial for understanding magnetism in solids.
