Quantum Anomalous Hall Effect in a Perovskite and Inverse-Perovskite Sandwich Structure
Long-Hua Wu, Qi-Feng Liang, Xiao Hu
Based on first-principles calculations, we propose a sandwich structure composed of a G-type anti-ferromagnetic (AFM) Mott insulator LaCrO grown along the [001] direction with…
Topological Properties of Electrons in Honeycomb Lattice with Kekulé Hopping Textures
Long-Hua Wu, Xiao Hu
Honeycomb lattice can support electronic states exhibiting Dirac energy dispersion, with graphene as the icon. We propose to derive nontrivial topology by grouping six neighboring…
Scheme to Achieve Silicon Topological Photonics
Long-Hua Wu, Xiao Hu
We derive in the present work topological photonic states purely based on silicon, a conventional dielectric material, by deforming a honeycomb lattice of silicon cylinders into a…
Possible Half Metallic Antiferromagnetism in a Double Perovskite Material with Strong Spin-Orbit Couplings
Madhav P. Ghimire, Long-Hua Wu, Xiao Hu
Using the first-principles density functional approach, we investigate a material PrMgIrO (PMIO) of double perovskite structure synthesized recently. According to the calcu…
Proposal for Manipulation of Majorana Fermions in Nano-Patterned Semiconductor-Superconductor Heterostructure
Long-Hua Wu, Qi-Feng Liang, Zhi Wang +1
We investigate a heterostructure system with a spin-orbit coupled semiconductor sandwiched by an s-wave superconductor and a ferromagnetic insulator, which supports Majorana fermio…
Electrically Tunable Topological State in [111] Perovskite Materials with Antiferromagnetic Exchange Field
Qi-Feng Liang, Long-Hua Wu, Xiao Hu
A topological state with simultaneous nonzero Chern number and spin Chern number is possible for electrons on honeycomb lattice based on band engineering by staggered electric pote…
