| dc.description.abstract | moving in a two dimensional space. We study the diusion property of a single particle by
measuring the mean square displacement as a function of time. At short times the particles
undergo unhindered self-diusion, at intermediate times they are hindered and conned in a
cage formed by the neighbors, and at long times the large step hoppings occur. These three
dierent motions are found in the melting state and the cage-eect disappears in the liquid state.
We also study the mobility of the particles by measuring the displacement distribution and its
deviation from Gaussian behavior. Non-Gaussian behavior is contributed by the hoppings
occuring in the cage-eect region. Some faster particles and relaxation of cages are found at
intermediate times. The shapes and sizes of cooperative motions are studied by examing the
correlations among the particles displacements in both longitudinal and transverse directions.
The string-like and vortex-like cooperative motions are both present and the sizes of the clusters
are measured. | en_US |
