“…As u 0 [ 0, it is clear from (11), (19), and (22) that depending on the sign of B, the solitary waves will be associated with either positive potential ð/ m [ 0Þ or negative potential ð/ m \0Þ. Therefore, there exists solitary waves associated with positive (negative) potential when B [ 0 ðB\0Þ.…”

An attempt has been made to study the multidimensional instability of dust-ion-acoustic (DIA) solitary waves (SWs) in magnetized multi-ion plasmas containing opposite polarity ions, opposite polarity dusts and nonthermal electrons. First of all, we have derived ZakharovKuznetsov (ZK) equation to study the DIA SWs in this case using reductive perturbation method as well as its solution. Small-k perturbation technique was employed to find out the instability criterion and growth rate of such a wave which can give a guideline in understanding the space and laboratory plasmas, situated in the D-region of the Earth's ionosphere, mesosphere, and solar photosphere, as well as the microelectronics plasma processing reactors.

Ion-acoustic (IA) solitons in a collisionless plasma consisting of positive and negative ions and superthermal electrons are studied by using the reductive perturbation method. The basic set of fluid equations is reduced to Korteweg-de Vries (K-dV) and modified Korteweg-de Vries (mK-dV) equations. It is found that both compressive and rarefactive solitons can be propagated in this system. Also it is shown that at critical concentration of positive ions mKdV solitons coexist. The effects of spectral index kappa, positive to negative ion density ratio and mass ratio of positive to negative ions on IA solitons structure are also discussed.

“…28 Laboratory observations in such systems of low-resistivity, multi-ion-species plasmas (mostly protons and carbon ions) revealed a phenomenon of simultaneous field penetration and plasma pushing. 29 In these experiments, the heavier-ion plasma component (carbon) is penetrated by the magnetic field at a rate much faster than that expected from diffusion, 30 whereas the light-ion plasma (protons) is reflected off the field front, acquiring velocities that are about twice the magnetic-field front propagation velocity. 31 The ions in the plasma penetrated by the magnetic field are also found to acquire non-negligible velocities relative to the magnetic-field propagation velocity.…”

Electron density evolution during a fast, non-diffusive propagation of a magnetic field in a multi-ion-species plasma Electron density evolution during a fast, non-diffusive propagation of a magnetic field in a multi-ion-species plasma We present spectroscopic measurements of the electron density evolution during the propagation of a magnetic-field front (peak magnitude $8 kG) through low-resistivity, multi-ion species plasma. In the configuration studied, a pulsed current, generating the magnetic field, is driven through a plasma that pre-fills the volume between two electrodes. 3D spatial resolution is achieved by local injection of dopants via an optimized laser blow-off technique. The electron density evolution is inferred from the intensity evolution of Mg II and B II-III dopant line-emission. The Doppler-shifted line-emission of the light boron, accelerated by the magnetic field is also used to determine the electric-potential-hill associated with the propagating magnetic field. Utilizing the same spectral line for the determinat...
