Mode coupling and resonance instabilities in quasi-two-dimensional dust clusters in complex plasmas
(American Physical Society, 2014-09-16)
Small quasi-two-dimensional dust clusters consisting of three to eleven particles are formed in an argon plasma under varying rf power. Their normal modes are investigated through their mode spectra obtained from tracking ...
Two-dimensional and three-dimensional Coulomb clusters in parabolic traps
(AIP Publishing, 2014-09-08)
We consider the shell structure of Coulomb clusters in an axially symmetric parabolic trap exhibiting a confining potential U_c(ρ,z)=(mω^2/2)(ρ^2+αz^2) . Assuming an anisotropic parameter α = 4 (corresponding to experiments ...
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 ...
