Stability of particle arrangements in a complex plasma.
It is shown that the stability of the vertical and horizontal confinement of colloidal "dust" particles levitating in a complex plasma appears as a nontrivial interplay of the external confining forces as well as the interparticle interactions and plasma collective processes such as the wake formation.
