Topological charge and bulk-surface correspondence for quad-helicoid surface states in topological semimetals with two glide-time-reversal symmetries
Taiki Yukitake, Shuichi Murakami
Quad-helicoid surface states (QHSSs) are unique surface states with two pairs of helicoid surface states in topological semimetals such as Dirac semimetals. So far, topologically p…

Double-helicoid surface states in Dirac semimetals protected by glide-time-reversal symmetry
Taiki Yukitake, Daisuke Hara, Shuichi Murakami
Recently, some monopole charges were defined for Dirac semimetals with symmetry (: glide, : time-reversal) in previous works, and the…
