Finite size effects on the Hamiltonian. (a) Simulated data with N = 50 and 10⁶ Monte Carlo runs for various ratios γ/α. (inset) Data collapse using the scaling factor ρ₀², suggesting an universal behavior at the beginning of the outbreak. (b) Initial decay of $\mathscr{H}$ compatible with power-law, $\mathscr{H}~{\tau }^{-\lambda }$. The exponent λ = 1/2 remains constant for different ratios γ/α, suggesting an universal behavior.
