Abstract: Based on the 2D star lattice with non-collinear orbital, we present an intriguing six-band tight-binding model for planar quantum anomalous Hall effect (PQAHE) with in-plane magnetization. Depending on the orientation of non-collinear orbital, the characterized… read more here.

Abstract: We introduce a novel mean field theory (MFT) around the exactly soluble two leg ladder limit for the planar quantum compass model (QCM). In contrast to usual MFT, our construction respects the stringent constraints imposed… read more here.
