Self-similarity in the shape of the regions of the correlated motions

A series of the molecular dynamics simulation has been carried out about th e fluids and the supercooled fluids of the two dimensional system. The syst em sizes are 10,000 atoms and 250,000 atoms. The shapes of the regions for the (linearly) correlated motion of atoms are very similar regardless of it s size. The fractal dimension is about 1.5 which has been calculated in the 2-D binary mixture supercooled fluids. The regions of this motion spread w idely for the bigger system, especially in the highly supercooled fluids an d glasses.
