It is found that the Dirac points at the $K$ and $K'$ points are generically moved to other locations in the Brillouin zone, but that they remain present when the Zeeman field $\\vec{\\Delta}(x)$ integrates to zero within a unit cell. A large variety of locations for the Dirac points is shown to be possible: when $\\vec\\Delta \\parallel \\hat{z}$ they are shifted from their original locations along the ","authors_text":"A.R.
