Heterogeneity in homogeneous nucleation from billion-atom molecular dynamics simulation of solidification of pure metal

Nucleation is a fundamental physical process, however it is a long-standing issue whether completely homogeneous nucleation can occur. Here the authors reveal, via a billion-atom molecular dynamics simulation, that local heterogeneity exists during homogeneous nucleation in an undercooled iron melt.
