Type-II Dirac line node in strained Na3N
Dongwook Kim, Seongjin Ahn, Jong Hyun Jung +4
Dirac line node (DLN) semimetals are a class of topological semimetals that feature band-crossing lines in momentum space. We study the type-I and type-II classification of DLN sem…

Band Topology and Linking Structure of Nodal Line Semimetals with Z2 Monopole Charges
Junyeong Ahn, Dongwook Kim, Youngkuk Kim +1
We study the band topology and the associated linking structure of topological semimetals with nodal lines carrying monopole charges, which can be realized in three-dimensi…
