Strain and onsite-correlation tunable quantum anomalous Hall phases in ferromagnetic (111) LaXO${}_3$ bilayers (X$=$Pd, Pt)

Hai-Shuang Lu, Guang-Yu Guo

Quantum anomalous Hall (QAH) phases in magnetic topological insulators are characterized by the scattering-free chiral edge currents protected by their nontrivial bulk band topolog…
