color coded. First column: Area functional M0, second column: perimeter functional M1, third column: euler functional M2.
For early times of spinodal decomposition the time dependent functionals (Fig. 4 and Fig. 5) vary for different threshold density values. However, for later times the functionals become constant functions of ρth due to the
emergence of well defined demixed domains. The functionals have their greatest variations at relative threshold values in the vicinity of the mixture parameter ρth/ρth,100' x. The variation of the functionals at ρth/ρth,100 ' x
decreases as time evolves due to the decrease of interfaces in the stage of domain coalescence. After the crossover time t∗c between the spinodal decomposition and domain growth phase the functionals become constant functions.
The area functionals M0 for large times approach the constant value of the complete surface V0 weighted with the
mixing parameter x: V (t → ∞) = V0x. Correspondingly the perimeter functionals M1converge towards the value of
the boundary length of the corresponding spherical cap. The Euler functional M2 converges to the constant number
of already demixed domains. For the extreme values of T on can observe peaks in M1 and M2 that originate from
an artefact of the numerical implementation: the calculation of functional derivatives is done via convolutions of the spherical harmonical decomposition leading to overshoots at sharp edges of density variations at pixel boundaries. Since the analysis in the main paper only depends on intermediate values of ρth this does not pose a problem.
The number of domains can readily be obtained as the value of the Euler functional M2 (Fig. 8 ). It counts the
number of connected domains and substracts the number of holes in the domains. Since for non-extreme threshold values (near the boundaries, e.g, ρth/ρth,100 = 0 and ρth/ρth,100 = 1) there are no holes in the domains, and the
