Article Synopsis
- Topology now helps describe the electronic structure of crystalline solids, with a focus on surface states of bulk insulating three-dimensional topological crystals.
- The study reveals that bismuth, usually seen as topologically trivial, actually has unique hinge states that are topologically protected and contribute to conducting modes instead of just surface states.
- The findings are backed by theoretical analysis and experiments, including scanning-tunneling spectroscopy and Josephson interferometry, confirming bismuth's classification as a higher-order topological insulator.
