Chiral topological phases in optical lattices without synthetic fields
Hoi-Yin Hui, Mengsu Chen, S. Tewari +1
Synthetic fields applied to ultracold quantum gases can realize topological phases that transcend conventional Bose and Fermi-liquid paradigms. Raman laser beams in particular are…
Quantum anomalous Hall state from spatially decaying interactions on the decorated honeycomb lattice
Mengsu Chen, Hoi-Yin Hui, Sumanta Tewari +1
Topological phases typically encode topology at the level of the single particle band structure. But a remarkable class of models shows that quantum anomalous Hall effects can be d…
Reordering Fractional Chern Insulators into Stripes of Fractional Charges with Long-Range Interactions
Mengsu Chen, V. W. Scarola
Long-range interactions drive some of the rich phenomenology of quasiparticle collective states in the fractional quantum Hall (FQH) regime. We test for analogues in models of frac…
Quantum anomalous Hall effect on star lattice with spin-orbit coupling and exchange field
Mengsu Chen, Shaolong Wan
We study the star lattice with Rashba spin-orbit coupling and exchange field and find that there exists the quantum anomalous Hall effect in this system and there are five energy g…
