Hitting a topological insulator with powerful pulses of circularly polarized laser light reveals what its electrons are doing – and how its surface switches f

Newswise — 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… [+6532 chars]
