MIT News: Is it topological? A new materials database has the answer. “In 2007, researchers predicted the first electronic topological insulators — materials in which electrons that behave in ways that are ‘topologically protected,’ or persistent in the face of certain disruptions. Since then, scientists have searched for more topological materials with the aim of building better, more robust electronic devices. Until recently, only a handful of such materials were identified, and were therefore assumed to be a rarity. Now researchers at MIT and elsewhere have discovered that, in fact, topological materials are everywhere, if you know how to look for them.”
