Role of dispersive waves in collisionless magnetic reconnection.

Simulations of collisionless magnetic reconnection show a dramatic enhancement of the nonlinear reconnection rate due to the formation of an open outflow region. We link the formation of this open configuration to dispersive whistler and kinetic Alfvén wave dynamics at small scales. The roles of these two waves are controlled by two dimensionless parameters, which allow us to identify regions o...

Kinetic simulations of collisionless magnetic reconnection in presence of a guide field

The results of kinetic simulations of magnetic reconnection in Harris current sheets are analyzed. A range of guide fields is considered to study reconnection in plasmas characterized by different β values, β > me/mi. Both an implicit Particle-in-Cell (PIC) simulation method and a parallel explicit PIC code are used. Simulations with mass ratios up to the physical value are performed. The simul...

The role of electron dissipation on the rate of collisionless magnetic reconnection

Particle simulations and analytic arguments are presented to demonstrate that the electron dissipation region, including the physics which breaks the frozen-in condition, does not affect the rate of reconnection in collisionless plasma. The result is a general consequence of the quadratic nature of the dispersion character of whistler waves, which control the plasma dynamics at small scales. Th...

Generation of Alfvén Waves by Small-Scale Magnetic Reconnection in Solar Spicules

Alfvén waves dissipation is an extensively studied mechanism for the coronal heating problem. These waves can be generated by magnetic reconnection and propagated along the reconnected field lines. Here, we study the generation of Alfvén waves at the presence of both steady flow and sheared magnetic field in the longitudinally density stratified of solar spicules. The initial flow is assumed to...

Collisionless reconnection using Alfvén wave radiation resistance

Patchy magnetic reconnection involves transient field-aligned current filaments. The spatial localization, transient time-dependence, and orientation of these current filaments means they must radiate torsional Alfvén waves. Radiation of wave energy does not come for free—it must load the current which acts as the radiative source. This loading ~radiation resistance! is proposed as the energy s...
