Mode Couplings and Conversions for Horizontal Dust Particle Pairs in Complex Plasmas
(IEEE Transactions on Plasma Science, 2013-04)
The normal modes for horizontal dust particle pairs in a complex plasma are investigated using two methods, a numerical calculation and a molecular dynamics simulation. The ion wakefield downstream of each particle and the ...
Determination of the levitation limits of dust particles within the sheath in complex plasma experiments
(Physics of Plasmas, 2012-01-23)
Experiments are performed in which dust particles are levitated at varying heights above the powered electrode in a radio frequency plasma discharge by changing the discharge power. The trajectories of particles dropped ...
Mode couplings and resonance instabilities in dust clusters
(Physical Review E, 2013-10-16)
The normal modes for three to seven particle two-dimensional (2D) dust clusters in a complex plasma are investigated using an N-body simulation. The ion wakefield downstream of each particle is shown to induce coupling ...
Dust particle pair correlation functions and the non-linear effect of interaction potentials
(IEEE Transactions on Plasma Science, 2019-07)
Dust temperature is a measure of the energy of the stochastic motion of a dust particle, and is a result of the combination of the Brownian motion and the fluctuations in the dust charge and confining electric field. A ...
Mode couplings and resonance instabilities in finite dust chains
(American Physical Society, 2015-05-08)
Employing a numerical simulation, the normal modes are investigated for finite, one-dimensional horizontal
dust chains in complex plasma. Mode couplings induced by the ion flow within the sheath are identified in the
mode ...
Dynamics of a Dust Crystal with Two Different Size Dust Species
(Advances in Space Research, 2006)
A self-consistent 3D model for a complex (dusty) plasma is used to study the effects of multiple-sized dust grains in a dust crystal. In addition to the interparticle forces, which interact through a Yukawa potential, the ...
One-dimensional vertical dust strings in a glass box
(Physical Review E, 2011-07-28)
The oscillation spectrum of a one-dimensional vertical dust string formed inside a glass box on top of the lower electrode in a gaseous electronics conference (GEC) reference cell was studied. A mechanism for creating a ...
Simple method to measure the interaction potential of dielectric grains in a dusty plasma
(Physics Review E, 2010-09)
A simple minimally perturbative method is introduced which provides the ability to experimentally measure both the radial confining potential and the interaction potential between two individual dust particles, levitated ...
Interaction force in a vertical dust chain inside a glass box
(Physical Review E, 2014-07-31)
Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
Vibrational Modes and Instabilities of a Dust Particle Pair in a Complex Plasma
(IEEE Transactions on Plasma Science, 2010-04-10)
Vibrational modes and instabilities of a dust-particle pair in a terrestrial aboratory complex plasma are investigated by employing an analytical method whereby the plasma wakefield induced by an external electric field ...
