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 ...
Dust as probe for horizontal field distribution in low pressure gas discharges
(Plasma Sources Science and Technology, 2014-06-23)
Using dust grains as probes in gas discharge plasma is a very promising, but at the same time very challenging method, as the individual external control of dust grains has to be solved. We propose and demonstrate the ...
Measurement of net electric charge and dipole moment of dust aggregates in a complex plasma
(Physical Review E, 2014-09-02)
Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from ...
Slow Plastic Deformation (Creep) of 2D Dusty Plasma Solids
(Physical Review Letters, 2014-07-09)
We report complex plasma experiments, assisted by numerical simulations, providing an alternative qualitative link between the macroscopic response of polycrystalline solid matter to small shearing forces and the possible ...
