Ground state charge occupation and electric field on links for m = −3.0 (a) and m = 3.0 (c) and \({g}_{{\rm{m}}}^{2}=0\). b Particle density as a function of m, for different system size L and \({g}_{{\rm{m}}}^{2}=0\). Ground state charge occupation and electric field on links for m = −3.0 (d) and m = 3.0 (f) in the presence of magnetic interactions with \({g}_{{\rm{m}}}^{2}=8/{g}_{{\rm{e}}}^{2}=4\). e Particle density as a function of m, for different system size L and \({g}_{{\rm{m}}}^{2}=8/{g}_{{\rm{e}}}^{2}=4\).
