“Not since the isolation of graphene has a new material generated as much excitement among physicists as the discovery of topological insulators.” Highlights in Nature vol 6 2010. A topological insulator is as an insulator that has a metallic boundary when placed next to a vacuum or an ordinary insulator (See for example J. E. Moore, Nature 464(2010)08916.) These exotic materials can possibly be used in technological applications such as spintronics and quantum computing.
