In recent experiments of strongly coupled complex plasmas (SCCPs), trapping-like phenomena of micro-sized dust particles were observed during propagation of large-amplitude dust-density waves. A small number of particles were observed being trapped and carried along with the waves. In the present paper, we study the similar trapping phenomena in two-dimensional SCCPs by using Brownian dynamics simulation. The trapping process and its new features arising from strong-coupling effects are investigated. In particular, similarities and differences between trapping in weakly coupled plasmas and SCCPs are discussed in detail.

    Recently, it was shown that it is possible to confine spherical dust clouds in a plasma. It was found that these dust clouds have a crystalline structure which differs noteably from the well known fcc, bcc and hcp order in extended crystalline systems. The experiments show that the particles...

    Usually, a three-dimensional dust cloud trapped into a plasma contains a dust-free region called void. This region can enter in an unstable state and its frontiers can oscillate. This succession of contractions and expansions is known as the heartbeat instability. This instability is...
