 abstract = {We study the two-dimensional assemblies of interacting colloidal
particles in a loosely focussed optical trap. As the optical confinement
is increased, the system becomes ordered and we investigate how these
crystallites maintain their order under externally imposed oscillation.
For small amplitudes, the crystalline order remains intact and the
system behaves like a rigid body as predicted by numerical simulations.
However, the rigidity breaks at large amplitudes, which we infer to be
caused by the anharmonic component of the confinement potential. These
studies are general enough to be applied to other physical systems
comprising ordered finite-sized assemblies under external dynamic
perturbation.},
