Topological crystalline semimetals in non-symmorphic lattices
Yige Chen, Heung-Sik Kim, Hae-Young Kee
Numerous efforts have been devoted to reveal exotic semimetallic phases with topologically non-trivial bulk and/or surface states in materials with strong spin-orbit coupling. In p…
Crystal structure and magnetism in -RuCl3: an ab-initio study
Heung-Sik Kim, Hae-Young Kee
-RuCl has been proposed recently as an excellent playground for exploring Kitaev physics on a two-dimensional (2D) honeycomb lattice. However, structural clarification of th…
Molecular orbital polarization in Na2Ti2Sb2O: microscopic route to metal-metal transition without spontaneous symmetry breaking
Heung-Sik Kim, Hae-Young Kee
Ordered phases such as charge- and spin-density wave state accompany either full or partial gapping of Fermi surface (FS) leading a metal-insulator or metal-metal transition (MMT).…
Magnetic Orders Proximal to the Kitaev Limit in Frustrated Triangular Systems: Application to BaIrTiO
Andrei Catuneanu, Jeffrey G. Rau, Heung-Sik Kim +1
Frustrated transition metal compounds in which spin-orbit coupling (SOC) and electron correlation work together have attracted much attention recently. In the case of 5 transiti…
Spin-orbit excitations and electronic structure of the putative Kitaev magnet -RuCl
Luke J. Sandilands, Yao Tian, Anjan A. Reijnders +5
Mott insulators with strong spin-orbit coupling have been proposed to host unconventional magnetic states, including the Kitaev quantum spin liquid. The 4 system -RuCl ha…
Predominance of the Kitaev interaction in a three-dimensional honeycomb iridate: from ab-initio to spin model
Heung-Sik Kim, Eric Kin-Ho Lee, Yong Baek Kim
The recently discovered three-dimensional hyperhoneycomb iridate, -LiIrO, has raised hopes for the realization of dominant Kitaev interaction between spin-orbit entangle…
