Topological insulators: how the deep controls the superficial
Institute for Solid State Physics and Optics, Wigner Research Centre for Physics, Hungarian Academy of Sciences, H-1525 Budapest, P.O. Box 49, Hungary
Topological insulators prevent current from passing through, but also ensure that it flows unimpeded from contact to contact on their surface. The combination of ideas from topology and band theory to explain and generalize this peculiar behaviour has had a transformative effect on condensed matter research.
