Superexchange and spin-orbit coupling in monolayer and bilayer chromium trihalides
Kok Wee Song, Vladimir I Fal'ko
We build a microscopic model to study the intra- and inter-layer superexchange due to electrons hopping in chromium trihalides (, X= Cl, Br, and I). In evaluating t…

Possible Nematic Order Driven by Magnetic Fluctuations in Iron Pnictides
Kok Wee Song, Yung-Ching Liang, Hokiat Lim +1
In this paper, instabilities of the isotropic metallic phase in iron pnictides are investigated. The relevant quartic fermionic interaction terms in the model are identified using…
