Symmetry-Protected Topological phases and Duality

Event Information:
Symmetry-Protected Topological (SPT) phases are, as the name suggests, topological phases without any conventional local order parameter, but distinct from the trivial phase only in the presence of a certain symmetry. The concept was first proposed by Gu and Wen in 2009 as a generalization of topological insulators discovered earlier. However, the prototypical example of the SPT phases, the Haldane gap phase in odd-integer spin chains, was discovered much earlier in the 1980s.
