Kitaev magnetism in honeycomb RuCl3 with intermediate spin-orbit coupling
Heung-Sik Kim, V. Vijay Shankar, Andrei Catuneanu +1
Intensive studies of the interplay between spin-orbit coupling (SOC) and electronic correlations in transition metal compounds have recently been undertaken. In particular, $j_{\rm…
Surface States of Perovskite Iridates AIrO; Signatures of Topological Crystalline Metal with Nontrivial Index
Heung-Sik Kim, Yige Chen, Hae-Young Kee
There have been increasing efforts in realizing topological metallic phases with nontrivial surface states. It was suggested that orthorhombic perovskite iridates are classified as…
Spin-orbital Entangled Molecular States in Lacunar Spinel Compounds
Heung-Sik Kim, Jino Im, Myung Joon Han +1
The entanglement of the spin and orbital degrees of freedom through the spin-orbit coupling has been actively studied in condensed matter physics. In several iridium-oxide systems,…
Topological and magnetic phases with strong spin-orbit coupling on the hyperhoneycomb lattice
Eric Kin-Ho Lee, Subhro Bhattacharjee, Kyusung Hwang +3
We study the general phase diagram of correlated electrons for iridium-based (Ir) compounds on the hyperhoneycomb lattice---a crystal structure where the Ir ions form a thre…
Electronic Structure and Magnetic Properties of Iridate Superlattice SrIrO/SrTiO
Kang-Hwan Kim, Heung-Sik Kim, Myung Joon Han
Motivated by an experimental report of iridate superlattices, we performed first-principle electronic structure calculations for SrIrO/SrTiO. Heterostructuring causes SrIrO…
