Interaction and filling-induced quantum anomalous Hall effect in ultra-cold neutral Bose-Fermi mixture on hexagonal lattice
Shang-Shun Zhang, Heng Fan, Wu-Ming Liu
We investigate the quantum anomalous Hall effect in a mixture of ultra-cold neutral bosons and fermions held on a hexagonal optical lattice. In the strong atom-atom interaction lim…

The Euler Number of Bloch States Manifold and the Quantum Phases in Gapped Fermionic Systems
Yu-Quan Ma, Shi-Jian Gu, Shu Chen +2
We propose a topological Euler number to characterize nontrivial topological phases of gapped fermionic systems, which originates from the Gauss-Bonnet theorem on the Riemannian st…
