“…EMHD theory has been applied in many regimes. Examples of subjects are to analyze the nonlinear vortices, [14][15][16] interactions in the wake of a laser pulse, 17 ultrafast penetration of magnetic field into collisionless plasma, and the dynamics of fast Z-pinches. 18 Recently, EMHD model has been used to investigate the plasma turbulence.…”

The general time evolution of tearing mode due to electron viscosity e from linear to nonlinear phase in the framework of electron magnetohydrodynamics ͑EMHD͒ is derived by quasilinear theory. Tearing mode grows exponentially in the linear phase and slows to an algebraic growth behavior ⌿ 1 ϰ ͑ e t͒ 2/3 ͑⌿ 1 is the magnetic flux͒ in the nonlinear phase. These two phases are separated by a transition during which the growth behavior is much different from that in the linear and nonlinear phases. It behaves as ⌿ 1 ϰ e 5/8 t 1/2 approximately.

“…One of the motivations of this work is to construct explicit analytical kinetic solutions that can describe the coherent magnetic vortex structures that have been observed in different PIC simulations of the interaction of an ultraintense ultrashort laser pulse with a plasma, 16,17 and also in the study in Ref. 18, with a ''Vlasov'' code, of the nonlinear evolution of the current filamentation instability ͑see Refs.…”

“…The magnetic field is known to play an important role in many astrophysical and magnetospheric phenomena that involve trapped particles; [7][8][9][10][11][12][13][14][15] as well as in the magnetic and inertial fusion. 16,17 However, due to the extreme complexity of the problem, the understanding of the particle trapping in magnetized plasma is still very limited.…”

Kinetic effects leading to the particle trapping are studied in a magnetized, inhomogeneous plasma configuration within the framework of the gyrokinetic theory in the frequency and spatial scale range that corresponds to the whistler waves. This treatment accounts for finite electron Larmor radius and polarization effects. A coherent nonlinear structure is found, which is identified as a magnetic vortex coupled with an electron hole. This novel electron hole is characterized by a strong magnetic field, and has a typical perpendicular size somewhat shorter than the electron collisionless skin depth. Electrons are trapped in the perpendicular direction by the combination of the electrostatic field, arising from the charge separation, and of the Lorentz force resulting from the propagation of the structure relative to the perturbed magnetic field lines. The trapping effects are restricted to the region at the center of the vortex. The size of this region is related to the electron Larmor-radius and to the Debye length.

“…These "magnetized" stimuli force us to carefully treat their wakefields. Some authors have noticed that these wakefields are electromagnetic and set up a related nonlinear theory based on fluid approximation [27,39]. Moreover, some efforts have been paid to experimentally probe the magnetic fields structure of wakefields [33].…”

Applying various stimuli to excite large-amplitude electrostatic structure within plasmas is a basic idea of plasma-based acceleration. However, because these stimuli are usually magnetized, whether or not their wakes within plasmas are purely electrostatic should be cautiously treated. By strict theory on self-consistent fields of charged particles, we make detailed investigations on the wakes of those magnetized stimuli and the acceleration by electromagnetic wakes.
