Topological insulator materials: From quantum mechanics to computers

By Eileen De Guire / May 20, 2012

Electrons on the surface of a topological insulator can flow with little resistance. Their spin and direction are intimately related; the direction of the electron determines its spin and in turn is determined by it. Credit: LBNL. Last week several press releases came out about new work on topological insulators. A topological insulator—more accurately, a…
