Crystallization in a mesoscopic system of charged dust particles: Molecular dynamics simulations

3D molecular dynamics simulation is performed in a dusty plasma with 6000 particles interacting via Yukawa potential in a box having a hard-wall or parabolic-type external confinements. Results show the presence of crystallization waves in the hard-wall confinement with HCP, FCC, and BCC lattice types. For the parabolic confinement, no crystallization wave takes place with only volume crystallization occurring with small amount of HCP, FCC, and BCC phases.
