Non-abelian hopf-euler insulators
We discuss a class of three-band non-Abelian topological insulators in three dimensions

Exact projected entangled pair ground states with topological Euler invariant
We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler

Representation-protected topology of spin-singlet -wave superconductors
We show that spin-singlet s-wave multiband superconductors have a topological phase
