    • In Fig. 3(b) we find | C (3 e x) | > | C (2 e x) | for T = 0.2 t, which is a feature inherited from the half-filled noninteracting system on the cubic lattice, where spin correlations at even Manhattan distances vanish.

    • Our particular interest was the search for the optimal parameters U / t and t / t ′ in terms of largest S Néel / N. For that reason we did not study the low U / t regime, where T Néel in the isotropic case is much smaller than the critical temperature at U / t = 8.

    • For t = t ′ our model is part of the universality class of the 3D S = 1 / 2 Heisenberg model and for t ≠ t ′ it belongs to the classical 3D Heisenberg universality class, both of which have a critical exponent of ν ≈ 0.71 [38, 5196 () PRLTAO 0031-9007 10.1103/PhysRevLett.80.5196].
