伽马射线暴外流中快速无碰撞重联的粒子模拟
Particle-in-cell simulations of fast collisionless reconnection in gamma-ray burst outflows
摘要：
我们提出了适用于磁主导对等离子体射流，如那些在伽马射线暴的条件下，无碰撞磁重联的粒子模拟的初步结果。我们发现类似的行为，以前的作者，但减少重新连接的效率。这是因为我们动态地包括了整个电磁场，并允许电场波动增长。虽然微弱，这些波动阻碍早期x点的形成周期性减速，甚至逆转流入。
英文摘要：
We present preliminary results of particle-in-cell simulations of collisionless magnetic reconnection for conditions that apply to magnetically dominated pair plasma jets such as those in gamma-ray bursts. We find similar behaviour to previous authors but with reduced reconnection efficiency. This results because we include the full electromagnetic field dynamically and allow electric field fluctuations to grow. Although weak, these fluctuations impede early x-point formation by periodically decelerating and even reversing the inflow.
