Nonlinear correction effects on transverse dust lattice waves in dusty plasmas

Abstract

The nonlinear correction effects on the transverse dust lattice mode wave are investigated in dusty plasinas. It is shown that the nonlinear correction effects on the dispersion relation increase with decreasing a/lambda(D), where a is the spacing of dust grains and a/lambda(D) is the Debye length. It is also found that the nonlinear correction effects enhance the frequency of the transverse dust lattice wave.
