New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction ...

Getting a look under the hood of topological insulators

Certain materials, like copper, conduct electricity very well. Other materials, like glass, do not. A certain kind of material, called a topological insulator, acts partially like one and partially like the other ― it ...
