{\prime}\)with Hubbard intra-patch and inter-patch density-density interaction. In this model, electronic instabilities towards valley polarization, intra-valley ferromagnetism, and inter-valley spin and charge order all occur at the same critical couplingλ. These 15 bilinears then form an adjoint...
