Epitaxially strained ultrathin LaNiO/LaAlO and LaNiO/SrTiO superlattices: a density functional theory + study
Heung-Sik Kim, Sang Hyeon Park, Myung Joon Han
By employing first-principles electronic structure calculations we investigate nickelate superlattices [LaNiO]/[LaAlO] and [LaNiO]/[SrTiO] with (001…
Engineering One-Dimensional Quantum Stripes from Superlattices of Two-Dimensional Layered Materials
J. H. Gruenewald, J. Kim, H. S. Kim +10
One-dimensional (1D) quantum systems, which are predicted to exhibit novel states of matter in theory, have been elusive in experiment. Here we report a superlattice method of crea…
Revealing frustrated local moment model for pressurized hyperhoneycomb iridate: paving a way toward quantum spin liquid
Heung-Sik Kim, Yong Baek Kim, Hae-Young Kee
There have been tremendous experimental and theoretical efforts toward discovery of quantum spin liquid phase in honeycomb-based-lattice materials with strong spin-orbit coupling.…
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…
