Hidden-symmetry-protected quantum pseudo-spin Hall effect in optical lattices
Jing-Min Hou, Wei Chen
We propose a scheme to realize a new Z_2 topological insulator in a square optical lattice. Different from the conventional topological insulator protected by the time-reversal sym…

Energy bands and Landau levels of ultracold fermions in the bilayer honeycomb optical lattice
Jing-Min Hou
We investigate the spectrum and eigenstates of ultracold fermionic atoms in the bilayer honeycomb optical lattice. In the low energy approximation, the dispersion relation has para…
