Dual topological nodal line and nonsymmorphic Dirac semimetal in three dimensions
Yun-Tak Oh, Hong-Guk Min, Youngkuk Kim
Previously known three-dimensional Dirac semimetals (DSs) occur in two types -- topological DSs and nonsymmorphic DSs. Here we present a novel three-dimensional DS that exhibits bo…

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…

Proposal of a spin-one chain model with competing dimer and trimer interactions
Yun-Tak Oh, Hosho Katsura, Hyunyong Lee +1
A new kind of spin-1 chain Hamiltonian consisting of competing dimer and trimer projection operators is proposed. As the relative strengths and signs of the interactions are varied…
