colloquium, Friday, May 15, 2020, , 11:30 am Piet Brouwer (Free University Berlin, Germany) Higherorder topological insulators and superconductors Topological insulators combine an insulating bulk with gapless states at their surfaces. This talk introduces "higherorder topological insulators", which are crystalline insulators with a gapped bulk and gapped crystalline boundaries, but topologically protected gapless states at corners or at edges of the crystal. I'll show that such "higherorder boundary states" are a generic boundary manifestation of the nontrivial bulk topology, if the bulk topology relies on a crystalline symmetry for its protection.
