Collisionless magnetic reconnection is a well known, but poorly understood phenomenon that is of critical importance to space plasma physics. This project seeks to understand the fundamental microphysics that produces collisionless reconnection by utilizing a variety of 2- and 3-dimensional computer codes to simulate the reconnection process. The computer codes will use hybrid techniques, where the ions are treated in kinetic particle terms and the electrons are treated as a magnetized fluid, and particle-in-cell (PIC) techniques where both ions and electrons are treated in full particle dynamical terms. The goal is to understand the microphysics that underlies all collisionless reconnection.

无碰撞磁重联是一种众所周知但知之甚少的现象，对空间等离子体物理至关重要。这个项目试图通过利用各种二维和三维计算机代码来模拟重新连接过程，来理解产生无碰撞重新连接的基本微物理。计算机代码将使用混合技术，其中离子以动力学粒子项处理，电子被视为磁化流体，以及粒子在单元(PIC)技术，其中离子和电子都以完全粒子动力学项处理。我们的目标是理解所有无碰撞重新连接背后的微观物理。
