Quantum Loop

Caption

Researchers at Princeton explored electrons in a magnetic material at room temperature and discovered that they engage in collective quantum behaviors called Weyl loops. Top: Photoemission spectroscopy snapshot of the quantum Weyl loops. Middle: A theoretical calculation related to the system's response to applied electromagnetic fields. The correspondence between the top and middle images reflects that the quantum Weyl loops are at the heart of the exotic electromagnetic properties of the topological quantum magnet. Bottom: Distribution of electrons on the surface of the topological quantum magnet. The sharp light-colored features are the quantum Weyl loops.
