Oscillations in a chain of rod-shaped colloidal particles in a plasma.
Oscillations in the one-dimensional chain consisting of rotatorlike particles levitating in a plasma are studied. General equations of motion for such a chain are derived. It is demonstrated that new oscillation modes associated with the rotational degrees of freedom appear for such a configuration. The dispersion characteristics of the modes are analyzed. Collective oscillations and equilibrium in lattices composed of cylindrical particles in a plasma are discussed.
