Stable topological phase transitions without symmetry indications in NaZnSbBi
Jaemo Jung, Dongwook Kim, Youngkuk Kim
We study topological phase transitions in tetragonal NaZnSbBi, driven by the chemical composition . Notably, we examine mirror Chern numbers that change without symm…
Stiefel-Whitney classes and topological phases in band theory
Junyeong Ahn, Sungjoon Park, Dongwook Kim +2
In this article, we review the recent progress in the study of topological phases in systems with space-time inversion symmetry . is an anti-unitary…
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…
