Abstract

Using the modified method of Brownian dynamics, the dynamics of macroparticles with a uniform metal coating in a plasma-dust monolayer under the action of laser radiation was simulated. The time dependences of the root-mean-square and average linear displacements of particles were calculated for different initial effective parameters of nonideality and different intensities of laser radiation. A relationship was established that connects the effective parameter of nonideality of the dusty plasma system of active particles with the maximum value of the mean linear displacement of particles.

Highlights

A dusty plasma monolayer is an actively investigated physical object with a number of unique properties [1,2,3,4,5,6,7,8,9,10,11]
The unusual properties of active matter are largely associated with the thermodynamic openness of such systems and, as a consequence, its study is important for solving fundamental problems of physics, chemistry and biology
The goal is to simulate the dynamics of charged macroparticles with a uniform metal coating in a plasma-dust monolayer under the action of laser radiation

Summary

Introduction

A dusty plasma monolayer is an actively investigated physical object with a number of unique properties [1,2,3,4,5,6,7,8,9,10,11]. The kinetic temperature of the macroparticles in the dusty plasma monolayer is much higher than the temperature of the surrounding heavy particles (neutrals and plasma ions) [6] This is due to the fact that the presence of a charge in the particles leads to the transfer of the electric energy of the gas discharge into the kinetic energy of the chaotic motion of particles in the plane of the monolayer. In this connection, the dusty plasma system can be considered as one of the options for the implementation of active matter [12,13,14,15,16,17]. To set it in modeling, it is necessary to use a non-standard approach, which is described below
