Event description: 

Phases of matter with the same symmetry may nevertheless be distinct. If a phase of matter has an energy gap that prevents excitations, and is distinct from a solid of weakly-bound atoms, we say that this phase of matter is a topological insulator. I will introduce the theory for a topological insulator with a symmetry commonly found in crystals, and describe the subsequent experimental discovery in the compound KHgSb.
