Title: Effects of interaction between plasma-flow fields and electrostatic fields in dusty plasmas

Abstract

Interaction between plasma-flow fields and electrostatic fields is considered as the most appropriate method for describing the characteristic properties of a dusty plasma. This method makes it possible to treat the openness of the dusty plasma systems and to describe the processes of self-organization and change in interaction between dust particles that are caused by the presence of plasma flows, in particular, to describe attraction between the dust particles at large distances, as well as the pairing of identically charged particles and the formation of complicated dusty structures including dusty plasma crystals. Interaction between the plasma-flow fields and electrostatic fields was previously taken into account only when considering particular problems but was not considered as the general characteristic property of the dusty plasma. It is emphasized that the model taking into account the plasma-flow fields and their interaction with the electrostatic fields is the only model that allows simultaneous explanation of all basic parameters characterizing the condensation of the dusty plasma to plasma crystals (coupling constant {gamma}, interparticle distance r{sub min}, and melting temperature T{sub d}) obtained in observations. Attraction between the dust particles at large distances leads to instability similar to gravitational instability, which was erroneously disregarded in previousmore » descriptions of the dust sound. The corresponding critical size is similar to the Jeans radius. As a result of such attraction, dusty systems are structured, and such structuring is similar to known gravitational structuring and can explain the observation of dusty structures in most laboratory experiments on the dusty plasma.« less

  • Linear and nonlinear propagation of dust-acoustic waves in a magnetized strongly coupled dusty plasma is theoretically investigated. The normal mode analysis (reductive perturbation method) is employed to investigate the role of ambient/external magnetic field, obliqueness, and effective electrostatic dust-temperature in modifying the properties of linear (nonlinear) dust-acoustic waves propagating in such a strongly coupled dusty plasma. The effective electrostatic dust-temperature, which arises from strong electrostatic interactions among highly charged dust, is considered as a dynamical variable. The linear dispersion relation (describing the linear propagation characteristics) for the obliquely propagating dust-acoustic waves is derived and analyzed. On the other hand, themore » Korteweg-de Vries equation describing the nonlinear propagation of the dust-acoustic waves (particularly, propagation of dust-acoustic solitary waves) is derived and solved. It is shown that the combined effects of obliqueness, magnitude of the ambient/external magnetic field, and effective electrostatic dust-temperature significantly modify the basic properties of linear and nonlinear dust-acoustic waves. The results of this work are compared with those observed by some laboratory experiments.« less
  • Since plasma parameters are altered by dust particles, studying how plasma parameters are related to dust particle growth is an important research issue in dusty plasma. In this paper, the correlation between plasma parameters (electron temperature and ion flux) and particle parameters (particle radius and density) is investigated in silane plasma both experimentally using a floating probe and theoretically by solving balance equations including an additional electron and ion loss to the dust. The results reveal that while the ion flux shows two peak values in the early discharge phase and at the end of coagulation phase, the electron temperaturemore » shows a sudden increase in the coagulation step and a gradual decrease in the molecular accretion step. Moreover, the calculated results with the secondary electron emission taken into account produce the best fit with the experimental results. Thus the study confirms that the secondary electron emission plays a crucial role in the coagulation of the dust particles.« less
  • The interaction between two dust-acoustic solitary waves (DASWs) in a three-dimensional magnetized dusty plasma has been investigated theoretically, using the extended Poincare-Lighthill-Kuo method. The analytical phase shifts after the interaction of the two solitary waves are derived. The effects of two types of isothermal ions, oblique collision of DASWs, the number densities of ions species to the density of charged dust grains ratio, the effective temperature of ions to the electron temperature ratio, and the adiabatic ratio of specific heats on the phase shifts are discussed. The results show that these parameters have strong effects on the phase shifts andmore » the trajectories of two DASWs after collision.« less
