Heartbeat instability as auto-oscillation between dim and bright void regimes
Aleksandr Pikalev, Mikhail Pustylnik, Christoph Räth +1
We investigated the self-excited as well as optogalvanically stimulated heartbeat instability in RF discharge complex plasma. Three video cameras measured the motion of the micropa…

Dim and bright void regimes in capacitively-coupled RF complex plasmas
A. Pikalev, I. Semenov, M. Pustylnik +2
We demonstrate experimentally that the void in capacitively-coupled RF complex plasmas can exist in two qualitative different regimes. The "bright" void is characterized by bright…
