Abstract

Wake-mediated interactions result in the coupling between wave modes in 2D complex plasma crystals, which can trigger the mode-coupling instability and cause melting. Spectra of phonons with out-of-plane polarization were studied experimentally in 2D plasma crystals during dedicated experiments on the mode-coupling instability. The kinematics of dust particles during the early stage of mode-coupling induced melting is explored. It is found that the formation of the hybrid mode causes the particle vibrations to partially synchronize at the hybrid frequency. The spatial orientation of the synchronization pattern correlates well with the directions of the maximal increment of the shear-free hybrid mode.
