Realizing Haldane Model in Fe-based Honeycomb Ferromagnetic Insulators
Heung-Sik Kim, Hae-Young Kee
The topological Haldane model (THM) on a honeycomb lattice is a prototype of systems hosting topological phases of matter without external fields. It is the simplest model exhibiti…
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.…
Pressure-Induced Confined Metal from the Mott Insulator Sr3Ir2O7
Yang Ding, Liuxiang Yang, Cheng-Chien Chen +12
The spin-orbit Mott insulator Sr3Ir2O7 provides a fascinating playground to explore insulator-metal transition driven by intertwined charge, spin, and lattice degrees of freedom. H…
Topological edge states in single layers of honeycomb materials with strong spin-orbit coupling
Andrei Catuneanu, Heung-Sik Kim, Oguzhan Can +1
We study possible edge states in single layers of honeycomb materials such as -RuCl and AIrO (A=Li, Na) with strong spin-orbit coupling (SOC). These two dimensional…
ARPES study of the Kitaev Candidate -RuCl
Xiaoqing Zhou, Haoxiang Li, Justin Waugh +7
-RuCl has been hinted as a spin-orbital-assisted Mott insulator in proximity to a Kitaev spin liquid state. Here we present ARPES measurements on single crystal -RuCl…
