摘 要: | Interplay of spin-orbit coupling(SOC) and electron correlation generates a bunch of emergent quantum phases and transitions, especially topological insulators and topological transitions. We find that electron correlation will induce extra large SOC in multi-orbital systems under atomic SOC and change ground state topological properties. Using the Hartree–Fock mean field theory, phase diagrams of px/py orbital ionic Hubbard model on honeycomb lattice are well studied. In general, correction of s...
