Topological Superconductors and Crystalline Insulators
Fu Liang, Harvard UniversityRecent
developments in topological insulators have inspired search for new
topological phases of electron systems. First I will describe ongoing
efforts towards finding a topological superconductor--an unconventional
superconductor which has a full pairing gap in the bulk and gapless
Andreev surface states. Next I will describe theory of new topological
phases in band insulators which have robust surface states protected by
point group symmetry.
