Digital Imaging and Analysis of Dusty Plasmas
(Advances in Space Research, 2004)
Dust particles immersed within a plasma environment, such as those found in planetary rings or cometary environments, will acquire an electric charge. If the ratio of interparticle potential energy to average kinetic energy ...
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 ...
Crystallization Dynamics of a Single Layer Complex Plasma
(Physical Review Letters, 2010-09)
We report a series of complex (dusty) plasma experiments, aimed at the study of the detailed time evolution of the recrystallization process following a rapid quench of a two-dimensional dust liquid. The experiments were ...
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 ...
Dusty Plasma Correlation Function Experiment
(Advances in Space Research, 2004)
Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge. If the ratio of the inter-particle potential energy to ...
Effect of Multi-Sized Dust Distribution on Local Plasma Sheath Potentials
(Advances in Space Research, 2006)
This work investigates the modification of a plasma sheath in a complex plasma due to the presence of dust particles with a specified size distribution. A self-consistent model for the plasma sheath is combined with a ...
Photophoresis on polydisperse basalt microparticles under microgravity
(Journal of Aerosol Science, 2014-10)
Photophoresis is a force which can dominate the motion of illuminated aerosols in low pressure environments of laboratory experiments, planetary atmospheres or protoplanetary disks. In drop tower experiments we quantified ...
A model of coagulation in dust clouds during grain charging
(Advances in Space Research, 2004)
Initially uncharged grains in space and laboratory plasma environments become charged due to currents driven by potential differences in the dusty plasma. Certain macroscopic effects such as coagulation of smaller grains ...
Spectral approach to transport in the two-dimensional honeycomb lattice with substitutional disorder
(Physical Review B, 2019-01)
The transport properties of a disordered two-dimensional (2D) honeycomb lattice are examined numerically using the spectral approach to the 2D percolation problem, characterized by an Anderson-type Hamiltonian. In our ...
