The complex pattern and propagation characteristics of cnoidal dust holes in dusty pair plasmas are analyzed in the weak amplitude limit. Dependent on the collective trapping conditions of the charged dust species and of other physically relevant parameters, a new class of electrostatic waves is presented, which supplements the known class of small amplitude waves. As the latter is typically based, in the lowest order, on a linearization of the governing Vlasov–Poisson system, this class of intrinsically nonlinear structures is claimed to be of paramount importance for the completion or at least correction of the theory of plasma turbulence and anomalous transport in electrostatically driven, collisionless, or weakly collisional plasmas.
