Complex plasmas consist of micron sized microparticles immersed into ordinary ion-electron plasmas. They are model systems to study dynamic phenomena at the kinetic level since the damping due to collisions with neutrals is several orders of magnitude smaller than in colloids. Here we report on experimental observations and numerical simulations of dynamic phenomena in complex plasmas: shocks, tsunami effect, and soliton collisions. Shocks, propagating discontinuities, are excited by large amplitude voltage pulses. As they propagate, they melt the lattice, which then re-crystallizes. The propagation of a pulse in an inhomogeneous lattice induces an increase of the amplitude of the pulse (“tsunami effect”) even in the presence of damping. The interaction between counterpropagating solitons is shown to be influenced by the lattice structure.
