Fig. 4.
(Left) Temperature dependence of overlap for different system sizes. Bigger system sizes seem to show sharper changes of overlap q with temperature. (Center) Spin glass susceptibility is plotted as a function of temperature for the studied system sizes. The strong variation with temperature is remarkable. Notice the strong system size dependence of susceptibility at lower temperatures. Currently, we cannot say whether this susceptibility will diverge with decreasing temperature in a thermodynamic limit, as the system sizes studied here are still quite small. One must study bigger system sizes to determine the possible divergence of the spin glass susceptibility at lower temperatures. (Right) Scaling collapse of the spin glass susceptibility using the scaling ansatz Eq. 1. The exponents are η ≃ −0.1, ν ≃ 1.0 with TK as shown in the Inset.
