Non-Abelian Hopf-Euler insulators
Wojciech J. Jankowski, Arthur S. Morris, Zory Davoyan +3
We discuss a class of three-band non-Abelian topological insulators in three dimensions that carry a single bulk Hopf index protected by spatiotemporal () inversion s…

Three-dimensional -symmetric topological phases with Pontryagin index
Zory Davoyan, Wojciech J. Jankowski, Adrien Bouhon +1
We report on a certain class of three-dimensional topological insulators and semimetals protected by spinless symmetry, hosting an integer-valued bulk inva…
