Quantum Hall effects in a non-Abelian honeycomb lattice
Quantum Hall effects in a non-Abelian honeycomb lattice
We study the tunable quantum Hall effects in a non-Abelian honeycomb optical lattice which is a multi-Dirac-point system. We find that the quantum Hall effects present different features with the change in relative strengths of several perturbations. Namely, the quantum spin Hall effect can be induced by gauge-field-dressed next-nearest-neighbor hopping, …
