(a) Mean squared displacements of Fe–Fe M(t), (b) autocorrelation function of traceless stress tensor S(t) and (c) time evoluted viscosity η(t) in FeNi fluid under Earth's core condition. The label ‘ICB’ and ‘CMB’ represent 330 GPa and 136 GPa, respectively. The S(0) is velocity-velocity autocorrelation function at t = 0.
