The nonlinear solitary structure of the dispersive Alfvén wave in an three-component plasma with hot positron, cold electron and ion is studied from the multi-fluid theory. It is found that when the equilibrium number density ratio of ion to electron is finite, there only exists the super-Alfvén rarefactive solitons. The increase of the ion concent...

Whistler-mode chorus and electromagnetic ion cyclotron waves have long been considered major causes of electron flux changes in the Earth’s outer radiation belt. Here, we report an ideal observation event from two identical satellites, during which the electron flux significantly decreases, followed by a partial recovery under the simultaneous exis...
Surface plasmon (SP) excitation in intense laser interaction with solid target can be exploited for enhancing secondary emissions, in particular efficient acceleration of high charge electron bunches. Previous studies have mostly used grating coupling to allow SP excitation, which requires stringent laser contrast conditions to preserve the structu...
The dynamics of the radiation belts are largely affected by the resonant interactions of energetic particles with plasma waves, such as whistler mode chorus waves. These waves play a direct and crucial role in the acceleration and loss of radiation belt electrons. The properties of these waves have been investigated thoroughly using various mission...
We present results of twisted plasma waves driven by twisted ponderomotive force. With beating of two, co-propagating, Laguerre-Gaussian (LG) orbital angular momentum (OAM) laser pulses with different frequencies and also different twist indices, we can get twisted ponderomotive force. Three-dimensional particle-in-cell simulations are used to demo...
Prior observations of the near-Sun solar wind (sunward of 0.25 au) identified frequent, intense plasma waves near the local electron cyclotron frequency ( f ce ), and its harmonics. In this Letter, it is shown that near- f ce wave properties are consistent with generation via interaction between the observing spacecraft’s ion wake and the ambient p...

The properties of dust inertial Alfvén waves (DIAWs) in a dusty plasma with the effects of polarization force are investigated. First, the dispersion equation is obtained from the fluid equations by considering the polarization force. Then, the energy balance equation is deduced by applying the Sagdeev pseudopotential method. It is shown that the polarization force affects the characteristics of DIAWs as well as the pseudopotential significantly. In addition, the existence of the polarization force changes the width of DIAWs. The present results may be helpful in further understanding the effect of polarization forces on the formation of linear and nonlinear structures of Alfvén waves in the laboratory plasma, astrophysical dusty plasma systems, planetary ring systems, cometary tails, etc.
