Topological Semimetals from first-principles
Heng Gao, Jörn W. F. Venderbos, Youngkuk Kim +1
We review recent theoretical progress in the understanding and prediction of novel topological semimetals. Topological semimetals define a class of gapless electronic phases exhibi…
Ferromagnetic nodal-line metal in monolayer {\em h}-InC
Sunam Jeon, Yun-Tak Oh, Youngkuk Kim
Based on first-principles calculations, we predict a new two-dimensional ferromagnetic material that exhibits exotic Fermi surface topology. We show that monolayer hexagonal indium…
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…
