摘要

最近，Alyousef等人。“超冷量子复合等离子体中尘埃-离子-声学调制包络结构的调制不稳定性：孤子、异常波和呼吸子”，物理学报，55(4),164 2025)报道。作者通过推导非线性Schrödinger方程（NLSE），研究了由带负电荷的静止尘埃颗粒、惯性离子和无惯性电子组成的超冷、无磁化、无碰撞量子等离子体中尘埃离子-声波的调制不稳定性和不同类型的局域结构。这一评论强调，这项工作可能提供有价值的见解，但他们的发现对非线性波特性的适用性是有限的，因为尘埃颗粒不太可能在具有如此高电子数密度的量子等离子体环境中保持稳定。

Comment on “Modulational Instability of Dust-Ion-Acoustic Modulated Envelope Structures in Ultracold Quantum Complex Plasmas: Solitons, Rogue Waves, and Breathers”

Recently, Alyousef et al. (Braz. J. Phys. 55(4), 164 2025) reported “Modulational Instability of Dust-Ion-Acoustic Modulated Envelope Structures in Ultracold Quantum Complex Plasmas: Solitons, Rogue Waves, and Breathers.” The authors studied modulation instability of dust ion-acoustic wave and different types of localized structures in an ultracold, unmagnetized, collisionless, quantum plasma consisting of negatively charged stationary dust grains, inertial ions, and inertialess electrons by deriving a nonlinear Schrödinger equation (NLSE). This comment highlights that the work may offer valuable insights but the applicability of their findings to nonlinear wave characteristics is limited, as dust particles are unlikely to remain stable in a quantum plasma environment with such high electron number densities.
