Abstract
The present paper gives a comparative evaluation of two approaches to the determination of the homogeneous nucleation rate in molecular dynamics computer experiments, viz. the methods of the mean lifetime of a metastable system and the mean time of the first passage to a cluster of a prescribed size. The crystal nucleation rate in a supercooled Lennard–Jones liquid has been determined in molecular dynamics simulation as a function of pressure at a reduced temperature T* = 0.55. The results of simulation have been compared with classical homogeneous nucleation theory. Good agreement between theory and the results of computer simulation has been found.
