Weyl semimetals in optical lattices: moving and merging of Weyl points, and hidden symmetry at Weyl points
We propose to realize Weyl semimetals in a cubic optical lattice. We find that there exist three distinct Weyl semimetal phases in the cubic optical lattice for different parameter ranges. One of them has two pairs of Weyl points and the other two have one pair of Weyl points in the Brillouin zone....
