Dispersion relations for circular single and double dusty plasma chains
D. V. Tkachenko, T. E. Sheridan, V. R. Misko
We derive dispersion relations for a system of identical particles confined in a two-dimensional annular harmonic well and which interact through a Yukawa potential, e.g., a dusty…
Charge fluctuations for particles on a surface exposed to plasma
T. E. Sheridan, A. Hayes
We develop a stochastic model for the charge fluctuations on a microscopic dust particle resting on a surface exposed to plasma. We find in steady state that the fluctuations are n…
Dusty plasma (Yukawa) rings
T. E. Sheridan, J. C. Gallagher
One-dimensional and quasi-one-dimensional strongly-coupled dusty plasma rings have been created experimentally. Longitudinal (acoustic) and transverse (optical) dispersion relation…
Power law behavior for the zigzag transition in a Yukawa cluster
T. E. Sheridan, Andrew L. Magyar
We provide direct experimental evidence that the one-dimensional (1D) to two-dimensional (2D) zigzag transition in a Yukawa cluster exhibits power law behavior. Configurations of a…
Dimensional phase transitions in small Yukawa clusters
T. E. Sheridan, K. D. Wells
We investigate the one- to two-dimensional zigzag transition in clusters consisting of a small number of particles interacting through a Yukawa (Debye) potential and confined in a…
