Exploring quantum electron highways with laser light: Spiraling laser light reveals how topological insulators lose their ability to conduct electric current on their surfaces. - Science Daily

Researchers used circularly polarized laser light to systematically probe the phase transition in which a topological insulator (TI) loses its quantum properties and becomes an ordinary insulator. The spiraling laser light generated harmonics -- much like the…

Topological insulators, or TIs, have two faces: Electrons flow freely along their surface edges, like cars on a superhighway, but can't flow through the interior of the material at all. It takes a sp… [+5823 chars]
