“…To demonstrate the significance of neutrals, we pick out a numerical example for warm dense hydrogen with the coupling and density parameters and , which are both evaluated for the total number density of protons and the temperature . In this particular situation, the ionization degree is provided in Davletov, Kurbanov & Mukhametkarimov (2020) as and formula (3.6) finally gives rise to , i.e. the screening length is decreased by approximately 19 %, which can have a drastic impact on theoretical predictions of various plasma properties.…”

In the classical treatment the screening phenomenon of electric fields in a plasma is solely caused by charged particles, i.e. electrons and ions. In contrast, the present consideration focuses on the role of neutrals in a situation when the correlations between the charged and neutral components of the plasma medium turn rather significant. The consideration is entirely based on the renormalization procedure for interparticle interactions, which takes into account collective events in the generalized Poisson–Boltzmann equation relating the true microscopic potentials with their effective macroscopic counterparts. A meaningful approach is proposed to analytically derive the screening length from an appropriate assumption on the asymptotic behaviour of the macroscopic potential at large interparticle separations. It is clearly demonstrated that the neutral component really affects the screening length when the plasma reaches states corresponding to warm dense matter conditions. It is also shown that, at certain critical values of the plasma parameters, the character of the screening changes from exponential to oscillatory decay.

“…For instance, recently, the Kelvin-Helmholtz instability in PID plasmas was investigated by Shadmehri and Downes. 14 In another study, Davletov et al examined the impact of dust species on the thermodynamic equilibrium of partially ionized plasma, 15 and more recently, Sharma and Jain investigated the radiative and gravitating modes in PID plasmas. 16,17 In addition, PID plasmas are useful in a wide variety of applications and are of utmost importance in plasma investigations and nuclear fusion.…”

Beltrami fields in partially ionized magnetized dusty plasma

The relaxed state of a magnetized four-component partially ionized dusty (PID) plasma is explored. PID plasma is composed of inertial electrons, positive ions, neutrals, and static negatively charged dust particles. When the neutrals are dragged along with the ions, the steady-state solution of vortex dynamic equations for inertial electron and ion species yields a triple Beltrami relaxed state, which is a linear combination of three single force-free fields and is characterized by three self-organized structures. The impact of plasma parameters such as Beltrami parameters and neutral (degree of ionization) and dust species densities on the nature of the relaxed state is investigated. Furthermore, the role of scale separation and its implication in space plasma are also presented. The present research will aid in elucidating the role of neutral and dust species in space, astrophysical, and laboratory plasmas.

The present paper investigates how an envelope solitary wave reflected and transmitted by one or several impurities in an inhomogeneous dusty plasma. By using the nonlinear Schrödinger equation and the molecular dynamics method, both the reflected waves and the transmitted waves due to impurities produced by an incident envelope solitary waves are given in the present paper. The results show that both the reflection and the transmission are usually envelope solitary waves if incident wave is an envelope solitary wave. The numbers of both the reflected and transmitted envelope solitary wave and the amplitudes of each reflected and the transmitted envelope waves depend on both the mass ratio of impurity to the dust particle and the impurity numbers in dust particle chain. This result may have potential applications. For example, both the reflection and the transmission produced by a given incident envelope solitary wave have the information of the number and the mass of the impurity.
