The thermal motion of a dust particle levitated in a plasma chamber is similar to that described by Brownian motion in many ways. The primary difference between a dust particle in a plasma system and a free Brownian particle is that in addition to the random collisions between the dust particle and the neutral gas atoms, there are electric field fluctuations, dust charge fluctuations, and correlated motions from the unwanted continuous signals originating within the plasma system itself.

Single Particle Dynamics in a Radio-Frequency Produced Plasma Sheath

Recently different research groups have investigated the motion of a single dust particle levitated in a rf plasma. Here we describe a highly resolved experiment where a single spherical melamine

Random motion of small solid particles is analyzed in a 3-D dusty plasma experiment under microgravity conditions. In this experiment, performed using the Plasmakristall-4 (PK-4) instrument on board

Effects of collision-enhanced charging on dust crystal

Numerical simulations of monolayer dust crystals in an RF complex plasma were performed to examine the crystal structure and quantify the effects of including the collision enhanced ion current in

Extracting forces from noisy dynamics in dusty plasmas.

Extracting environmental forces from noisy data is a common yet challenging task in complex physical systems. Machine learning (ML) represents a robust approach to this problem, yet is mostly tested

Active Brownian particle in homogeneous media of different viscosities: numerical simulations.

This paper proposes simple corrections to the basic theory of overdamped active Brownian motion, which allow one to calculate the effective diffusion coefficient and the persistence length of a self-propelled Brownian particle in a medium with any dynamic viscosity.

Experimental study of the nonreciprocal effective interactions between microparticles in an anisotropic plasma

It is found that even small charge changes of one particle, caused by its thermal motion in a wake field of another particle, can lead to a significant change in the effective (measurable) interaction between the particles.

Dust Particle Pair Correlation Functions and the Nonlinear Effect of Interaction Potentials

Dust kinetic temperature is a measure of the energy of the stochastic motion of a dust particle and is a result of the combination of the Brownian motion and the fluctuations in the dust charge and

The Brownian motion of a single particle in the plasma sheath is studied to separate the effect of stochastic heating by charge fluctuations from heating by collective effects. By measuring the

Exploring the wake of a dust particle by a continuously approaching test grain

The structure of the ion wake behind a dust particle in the plasma sheath of an rf discharge is studied in a two-particle system. The wake formation leads to attractive forces between the negatively

Interaction force in a vertical dust chain inside a glass box.

The sloshing and breathing modes of small cluster oscillations are employed to examine the relationship between system rf power and the particle charge and plasma screening length inside the glass box and results indicate that both the screening length and dust charge decrease as rfPower inside the box increases.

Charge-fluctuation-induced heating of dust particles in a plasma.

Analytical evaluations and numerical simulation show that charge fluctuations provide an effective source of energy and can heat the dust particles up to several eV, in conditions close to experimental ones.

A particle-in-cell simulation method is shown effective in modeling strongly coupled plasmas, exhibiting good energy conservation properties and good resolution of the dust-particle interaction. For

Two-particle distribution and correlation function for a 1D dusty plasma experiment.

In statistical theory, g(2) is usually said to be dominated by the randomness of collisions, but here it is found that it is dominated by collective oscillatory modes.

Experimental investigation of particle heating in a strongly coupled dusty plasma

Highly chargeddust particles in a plasma can be strongly coupled when their kinetic temperature is low. This temperature is determined by a balance of heating and gas cooling. The heating is believed
