Magnetic Reconnection
Dynamics of Collisionless Reconnection in Three-dimensional Open System
 We have developed electromagnetic particle simulation method for three-dimensional
open system and study the triggering mecha-nism of collisionless reconnection
and its dynamical behavior. Figure shows that two magnetic islands are
formed as a result of magnetic reconnection and move in the downstream
while being kinked.

Triggering Mechanism of Collisionless Reconnection
 Two-dimensional particle simulation studies have revealed that there are
two causes lead-ing to the excitation of collisionless reconnec-tion, i.e.,
anomalous resistivity generated by drift-kink instability, and pressure
tensor effect originating from complex particle motion. Figure shows the
current density profile when collisionless reconnection fully develops.
