均匀电场和磁场中电子对产生的动力学观点

Dynamical view of pair creation in uniform electric and magnetic fields

Naoto Tanji

摘要:

研究了均匀经典电磁场中的对产生(Schwinger机制),着重研究了产生粒子分布的时间演化。还介绍了随时间变化的场分布的时间演化以及反反应的影响。受重离子碰撞初始阶段可能形成的磁流管的启发,我们研究了平行于电场的磁场的效应,发现磁场使费米子系统的演化加快。

英文摘要:

Pair creation in a uniform classical electromagnetic field (Schwinger mechanism) is studied focusing on the time evolution of the distribution of created particles. The time evolution of the distribution in time-dependent fields is also presented as well as effects of back reaction. Motivated by the Glasma flux tube, which may be formed at the initial stage of heavy-ion collisions, we investigate effects of a magnetic field parallel to an electric field, and find that the magnetic field makes the evolution of a fermion system faster.
