“…It is shown that without the external electric field ion radial distributions agree with the results obtained in [1][2][3][4]6]. The external electric field leads to the disturbance of the spherical symmetry of plasma parameters around the dust particle.…”

“…In Fig.2, it can be also seen that the function p(E )Q has a maximum for some value of the external electric field as it was predicted with the help of a simple analytical estimation [6] and can be explained by the field ionization of trapped ions from a dusty quasi-atom.…”

“…From MC calculations presented in Fig.2, it follows that for a given ion mean free path, l i = 10λ i , and for small values of dimensionless electric fields E = e 0 E z λ i /2T i , the function p(E )Q is almost independent of the value of the dust particle charge. It means that the displacement of ions in the cloud around the dust particle is determined by a residual elastic force acting on the temporarily trapped ions and is inversely proportional to the dust particle charge [6]. For E > 0.3, a weak systematic growth of induced dipole moment with the increase of dust particle charge is observed.…”

“…For small external electric fields, the polarizability α of dusty "quasi-atoms" is very large, (α ∼ λ 3 i >> r 3 0 ). In strong external electric fields, the coefficient of polarizability α(E ) is a decreasing function of the external electric field probably due to field ionization [6].…”

The effect of plasma polarization around a negatively charged dust particle is investigated with the help of Monte Carlo simulation of ion trajectories in the electric field of the dust particle and an external electric field. The induced dipole moment of such a system was estimated in a wide range of dust particle and plasma parameters. It is shown that the dipole moment is very large, and has a non-monotonous dependence on the external electric field. For a small external electric field, it weakly depends on the charge of the dust particle. The dipole moment reduces with the decrease of ion mean free path.

“…Collisions with charge exchange between ions and atoms can lead to a new kind of forces. 14 In the experimental works, 15 formation of the vertical chain of dust particles, the authors used a special trap in the discharge of a homogeneous gas. In this paper, we present the results of experimental and theoretical investigations of the influence of plasma composition on the structural properties of plasma-dust formations.…”

The role of gas composition in plasma-dust structures in RF discharge

The influence of a mixture of light and heavy gases, i.e., helium and argon, on plasma-dust structures in the radiofrequency discharge has been studied. The dust chains in the sheath of the radiofrequency discharge, the average distance between the dust particles and their chains, have been analyzed. A significant effect of small amounts of argon on the correlation characteristics of dust particles has been observed. The results of numerical simulation of ion and electron drift in the mixture of helium and argon are presented. It is shown that even 1% of argon admixture to helium produces such an effect that argon ions become the main components of the discharge, as they drift with lightweight helium forming a strongly anisotropic velocity distribution function.

The paper presents the study of oscillations in the two-dimensional Yukawa liquids where the interparticle interaction potential in addition to the Yukawa term has the dipole-dipole interaction term. The frequency of longitudinal oscillations was studied using the Fourier transform of the velocity autocorrelation function. It was found that in the two-dimensional Yukawa liquids the longitudinal oscillation frequency of particles becomes sensitive to variations in the coupling parameter if even weak additional dipole-dipole interaction between particles exists.
