Crystallographic T-duality

Kiyonori Gomi, Guo Chuan Thiang

We introduce the notion of crystallographic T-duality, inspired by the appearance of -theory with graded equivariant twists in the study of topological crystalline materials. Be…

Crystallographic bulk-edge correspondence: glide reflections and twisted mod 2 indices

Kiyonori Gomi, Guo Chuan Thiang

A 2-torsion topological phase exists for Hamiltonians symmetric under the wallpaper group with glide reflection symmetry, corresponding to the unorientable cycle of the Klein bottl…
