Figure 2. Averaged energies versus the coupling strength uab. (a) The averaged energy $\left\langle {E}_{{\rm{a}},{\rm{b}}}\right\rangle $ versus the coupling strength uab. Nonlocal MS occurs at a critical point uab = uc = 2.2 under constant coupling. In contrast, by applying occasional coupling, we find that the critical behavior disappears, here T = 0.5, θ = 0.5. (b) The averaged interaction energy $\left\langle {E}_{\mathrm{int}}\right\rangle $ versus uab. Similarly, here we find that the original critical behavior under constant coupling disappears by applying occasional coupling, here T = 0.5, θ = 0.5.
