Abstract: C1.00242 : Study of Transient Nuclei near Freezing
Author:
The molasses tail in dense hard core fluids is investigated by
extensive event-driven molecular dynamics simulation through
the orientational autocorrelation functions. Near the fluid-
solid phase transition, there exist three regimes in the
relaxation of the pair orientational autocorrelation function,
namely the kinetic, molasses (stretched exponential), and
diffusional power decay. The density dependence of both the
molasses and diffusional power regimes are evaluated and the
latter compares with theoretical predictions in three
dimensions. The largest cluster at the freezing density of only
a few sphere diameter in size persist for only about 30
picoseconds ($\sim 2.8 \times 10^{-11}$[s]).
The most striking observation through the bond orientatinal
order parameter is the dramatic increase of the cluster size as
the freezing density is approached.
