Journal ArticleDOI
Direct observation of mode-coupling instability in two-dimensional plasma crystals.
Lénaïc Couëdel,Vladimir Nosenko,Alexei V. Ivlev,S. K. Zhdanov,Hubertus M. Thomas,Gregor E. Morfill +5 more
TL;DR: It is unambiguously demonstrated that the melting occurs due to the resonance coupling between two of the dust-lattice modes, and the variation of the wave modes with the experimental conditions, reveals exceptionally good agreement with the theory of mode-coupling instability.
Journal ArticleDOI
Residual dust charges in discharge afterglow.
TL;DR: An on-ground measurement of dust-particle residual charges in the afterglow of a dusty plasma was performed in a rf discharge and it was found that positively charged, negatively charged, and neutral dust particles coexisted for more than 1 min after the discharge was switched off.
Journal ArticleDOI
Mixed-mode oscillations in complex-plasma instabilities.
TL;DR: It is shown that some instabilities can be described by mixed-mode oscillations often encountered in chemical systems or neuronal dynamics and studied through dynamical system theories.
Journal ArticleDOI
Self-excited void instability in dusty plasmas: plasma and dust cloud dynamics during the heartbeat instability
TL;DR: In this paper, the authors investigated correlations between physical processes in the plasma volume and the dust cloud motion through experimental results and found that the observed instabilities are strongly dependent on local ionisation conditions.
Journal ArticleDOI
Wave mode coupling due to plasma wakes in two-dimensional plasma crystals: in-depth view
Lénaïc Couëdel,S. K. Zhdanov,Alexei V. Ivlev,Vladimir Nosenko,Hubertus M. Thomas,Gregor Morfill +5 more
TL;DR: In this paper, the authors predict a number of distinct fingerprints to be observed upon the instability onset, such as the emergence of a new hybrid mode, a critical angular dependence, a mixed polarization, and distinct thresholds.
