a \(\eta (T,\dot{\gamma })\) is plotted as a function of \(\dot{\gamma }\), and b \(\eta (T,\dot{\gamma })/{\eta }_{0}(T)\) is plotted as a function of \(\dot{\gamma }/{\dot{\gamma }}_{c}\). Symbols of different colors represent values at different T; T = 0.8 (yellow), 0.7 (purple), 0.6 (green), 0.55 (cyan), 0.5 (orange), 0.48 (blue), 0.46 (red), and 0.45 (black). In a, closed symbols indicate the equilibrium values η0(T). Black line indicates \(\eta ={\eta }_{0}\propto {\dot{\gamma }}^{0}\), whereas blue line indicates \(\eta \propto {\dot{\gamma }}^{-\nu }\) with ν ≃ 0.71. In b, the vertical dotted line indicates the location of \({\dot{\gamma }}_{c}\).
