| contents | The phenomenon of nonlinear wave mixing is investigated in a Yukawa one-component plasma using two-dimensional classical Langevin molecular dynamics simulations. The wave spectrum indicates that nonlinear interactions between the excited modes are primarily governed by a three-wave mixing mechanism, as confirmed by bispectral analysis. In particular, the mixing characteristics observed in the simulations closely resemble those reported in previous numerical studies of the forced Korteweg-de Vries (fKdV) model [ Phys. Plasmas 29, 032303 (2022)]. This similarity further validates the applicability of the fKdV fluid model in capturing the weakly nonlinear dynamics of dusty plasmas with reasonable accuracy. |
