Higher-order topological band structures

19 Aug 2020 Trifunovic Luka Brouwer Piet W.

The interplay of topology and symmetry in a material's band structure may result in various patterns of topological states of different dimensionality on the boundary of a crystal. The protection of these "higher-order" boundary states comes from topology, with constraints imposed by symmetry... (read more)
