Abstract

This paper investigates the dynamics of crystalline clusters observed in Molecular Dynamics (MD) studies conducted earlier (Yadav et al., 2023) for ultra-cold neutral plasmas. An external oscillatory forcing is applied for this purpose, and the evolution is tracked with the help of MD simulations using the open-source LAMMPS software. Interesting observations relating to cluster dynamics are presented. The formation of a pentagonal arrangement of particles is also reported.

强耦合超冷中性等离子体中振荡外力作用下屏蔽云的演变

本文研究了早先针对超冷中性等离子体进行的分子动力学（MD）研究（Yadav 等人，2023 年）中观察到的晶体团簇动力学。为此应用了外部振荡强迫，并在使用开源 LAMMPS 软件进行 MD 模拟的帮助下跟踪其演化过程。研究提出了与团簇动力学有关的有趣观察结果。此外，还报告了五边形粒子排列的形成。

期刊介绍： Physica D (Nonlinear Phenomena) publishes research and review articles reporting on experimental and theoretical works, techniques and ideas that advance the understanding of nonlinear phenomena. Topics encompass wave motion in physical, chemical and biological systems; physical or biological phenomena governed by nonlinear field equations, including hydrodynamics and turbulence; pattern formation and cooperative phenomena; instability, bifurcations, chaos, and space-time disorder; integrable/Hamiltonian systems; asymptotic analysis and, more generally, mathematical methods for nonlinear systems.
