Motivated by the recent experiment realizing bidirectional spin-orbit-coupledBose-Einstein condensates (BEC), we theoretically explore the properties ofrepulsive fermions in the two-dimensional (2D) optical lattice with suchnon-Abelian gauge fields. Within the mean-field level, we find a novel phase oftopological antiferromagnetic (TAFM) order which incorporates both thenon-trivial topology due to spin-flip hopping and spontaneous symmetry breaking(SSB) for the in-plane spin order. We argue that the appearance of such a phaseis generic for repulsive fermions in Chern bands achieved through spin-orbitcoupling. Our work paves the way for further studies of fermionicgeneralization of 2D non-Abelian spin-orbit-coupled quantum gases.
