Parallel and anti-parallel helical surface states for topological semimetals
Abstract Weyl points, carrying a Z-type monopole charge $$C$$ C , have bulk-surface correspondence (BSC) associated with helical surface states (HSSs). When | $$C$$ C | $$>1$$ > 1 , multi-HSSs can appear in a parallel manner. However, when a pair of Weyl points carrying $$C$$ C $$=\pm 1$$ = ±...
