Equilibrium molecular dynamics simulations reveal a transition from $\\kappa \\sim T^{-2}$ scaling below $T_c$ to $\\kappa \\sim T^{-1/2}$ above, contrasting with conventional $\\kappa \\sim T^{-1}$ behavior. This anomalous scaling correlates with the long-scale characteristic timescale $\\tau_2$ obtained from double exponential fitting of the heat current autocorrelation function.
