FIG. 1.

MD simulation of Yukawa system for the case of hard-wall confinement (case ). PDFs of -component of displacements (dots) in units of , plotted for different time lags . The full curve in (a) is a Gaussian with the same standard deviation, and the full curves in (b)–(d) are fits of the PDF’s core by a stretched-Gaussian given by Eq. (1) with values of (b), (c), and (d).

FIG. 6.

Distribution of local order parameters (calculated by using 12 nearest neighbors) obtained from 3D MD simulations of soft Yukawa systems. The color code indicates the density of points in the parameter space. The order parameters for ideal hcp and fcc crystals are also indicated, and the borders of the domains for crystalline and liquidlike systems (corresponding to coupling parameters and , respectively, and for ) are drawn as ellipses.
