Kinetic theory and simulation of collisionless tearing in bifurcated current sheets
Observations from the Earth’s geomagnetic tail have established that the current sheet is often bifurcated with two peaks in the current density. These so-called bifurcated current sheets have also been reported in a variety of simulations and often occur in conjunction with significant temperature anisotropy. In this work, a new self-consistent Vlasov equilibrium is developed that permits both...
متن کاملKinetic theory for transverse optomechanical instabilities.
We investigate transverse symmetry-breaking instabilities emerging from the optomechanical coupling between light and the translational degrees of freedom of a collisionless, damping-free gas of cold, two-level atoms. We develop a kinetic theory that can also be mapped on to the case of an electron plasma under ponderomotive forces. A general criterion for the existence and spatial scale of tra...
متن کاملWaves and Instabilities in Collisionless Shocks
By scattering particles and causing dissipation, waves in a collisionless shock play a role similar to collisions in an ordinary gas. In describing the waves and instability that occur near a shock three regions must be considered: (1) the transition region, (2) the upstream region, and (3) the downstream region. The transition region is usually characterized by an abrupt broadband burst of ele...
متن کاملKinetic Vlasov Simulations of collisionless magnetic Reconnection
A fully kinetic Vlasov simulation of the Geospace Environment Modeling (GEM) Magnetic Reconnection Challenge is presented. Good agreement is found with previous kinetic simulations using particle in cell (PIC) codes, confirming both the PIC and the Vlasov code. In the latter the complete distribution functions fk (k = i, e) are discretised on a numerical grid in phase space. In contrast to PIC ...
متن کاملElectromagnetic ion beam instabilities: Oblique pulsations
We present results of a two-dimensional hybrid simulation of the electromagnetic proton beam instability. We show that for a case of cold and rather high density proton beam the oblique right-handed resonant modes play an important role. The interaction of these modes with the beam protons causes significant beam density fluctuations. At the nonlinear stage the oblique modes give rise to a beam...
