Evolution of shielding cloud under oscillatory external forcing in strongly coupled ultracold neutral plasma

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.
