标题： Nonlinear modulation of transverse dust lattice waves in complex plasma crystals

摘要： 在传播于一维尘埃等离子体晶体中的横向尘埃晶格波中，研究了调制不稳定性（MI）的出现。 与鞘层电场的固有非线性相关的振幅调制机制被证明在某些条件下会破坏载波波，可能导致局域包络激发的形成。 给出了不稳定性增长率和阈值的显式表达式并进行了讨论。 显示英文摘要

摘要： The occurrence of the modulational instability (MI) in transverse dust lattice waves propagating in a one-dimensional dusty plasma crystal is investigated. The amplitude modulation mechanism, which is related to the intrinsic nonlinearity of the sheath electric field, is shown to destabilize the carrier wave under certain conditions, possibly leading to the formation of localized envelope excitations. Explicit expressions for the instability growth rate and threshold are presented and discussed.
