Eden clusters in three-dimensions and the Kardar-Parisi-Zhang universality class

الأصل · EN

We present large-scale simulations of radial Eden clusters in three-dimensions and show that the growth exponent is in agreement with the value β=0.242 accepted for the Kardar-Parisi-Zhang (KPZ) universality class. Our results refute a recent assertion proposing that radial Eden growth in d=3 belongs to a universality class distinct from KPZ. We associate the previously reported discrepancy to a slow convergence to the asymptotic limit. We also present the skewness and kurtosis in the roughening regime for flat geometry in 2+1 dimensions.
