“…On the other hand, in the absence of EPC (g = 0), the RSOC splits the spin textures-see, e.g. figures 1(a) and (c), shifting the vHs away from the half-filling, while preserving the FSN [47,48]. This gives rise to instabilities in the particlehole channel, except when t/t R = 0, where a WSM emerges.…”

“…Then, it is imperative to compare these cases with ours, highlighting both their similarities and differences. For instance, for the repulsive Hubbard model in the half-filled square lattice, the inclusion of the RSOC leads to the emergence of novel magnetic phases, which may include spiral and striped ones; away from the half-filling, ferromagnetism may appear [47,48,58,59,[61][62][63]. This occurs due to the spin-flip term in the RSOC, which disfavors the staggered antiferromagnetic ground state of the half-filling, suppressing the charge gap, while keeping gapless spin excitations.…”
