Within the kinetic approach the velocity and the charge distributions of grains in stationary dusty plasmas are calculated and the relations between the effective temperatures of such distributions and plasma parameters are established. It is found that the effective temperature which determines the velocity grain distribution could be anomalously large due to the action of accelerating ionic bombarding force. The possibility to apply the results obtained to the explanation of the increasing… 

New microscopic and macroscopic variables in dusty plasmas

The kinetic theory of dusty plasmas, in which the absorption of electrons and ions by dust particles is the dominating interaction process, is derived from first principles. The charging process is

Electron density fluctuations in collisional dusty plasma with variable grain charge.

The kinetic theory of electric fluctuations in a collisional weakly ionized dusty plasma is formulated with due regard to the grain charging dynamics to derive correlation spectra in isothermal and nonisothermal plasma.

Velocity distribution of dust particles localized in a plasma sheath near an electrode was found in a number of experiments. Velocity dispersion indicated that the kinetic temperature of dust grains

Electric Charge of Dust Particles in a Plasma

The problem of calculation of the electric charge of dust particles in a plasma is considered from different points of view. At first the charging of polarizable dust particles is studied within the

Kinetic Effects in Colloidal and Dusty Plasmas

Kinetic effects in two plasma-like systems, similar due to the presence of high charged mesoscopic particles, are investigated. Longitudinal and transverse waves in colloidal crystals are

Statistical theory of dusty plasmas: Microscopic description and numerical simulations

The first principles of statistical mechanics are used to formulate the basic points of kinetic theory of dusty plasmas. Equations for microscopic phase densities of plasma particles and grains are

Negative drag force on finite-size charged dust grain in strongly collisional plasma

The drag force on finite-size charged conductive spherical dust grain stationary moving in strongly collisional weakly ionized plasmas is studied numerically within the drift-diffusion approximation.

Mechanism of diffusion of positively charged dust particles in a photoemission cell under microgravity conditions

The decay of a dusty plasma in a photoemission cell under microgravity conditions is investigated on the basis of the method of nonlocal moments. It is founds that plasma decay in space experiments

Equilibrium probability distribution of a conductive sphere's floating charge in a collisionless, drifting Maxwellian plasma.

This paper derives analytic charge probability distributions up to normalizing constants for flowing plasmas and arbitrarily large spheres, finding that these distributions also have good Gaussian approximations, with analytic expressions for their mean and variance.
