Γ extracted at different symmetry breaking strengths α (different shapes) becomes indistinguishable for α < 10−5 illustrating the α independence. Close to the critical temperature Tc we find Γ ~ ∣T−Tc∣ in agreement with the overdamped Ginzburg–Landau prediction (dashed line). Deep within the superconducting phase T ≪ Tc the rate saturates. Note \(\mathop{\lim }\nolimits_{T\to {T}_{{{{{{{{\rm{c}}}}}}}}}}\Gamma (T)=0\), indicating the critical slowing down.
