等离子体中电子自旋效应的Particle-in-Cell模拟

Particle-in-Cell simulations of electron spin effects in plasmas

G. Brodin, A. Holkundkar, M. Marklund

摘要:

在这里,我们已经开发了一个粒子在细胞的代码占磁偶极子力和磁化电流与电子自旋。相对于磁场,电子被分成自旋向上和自旋向下的粒子群,其中磁偶极子力对两种粒子以相反的方向作用。为了验证程序的有效性,我们研究了平行于外磁场传播的电磁脉冲产生的尾流场。所产生的尾流场的属性示出与以前的理论结果是在良好的定量协议。讨论了代码的推广以考虑更多的量子效应

英文摘要:

We have here developed a particle-in-cell code accounting for the magnetic dipole force and for the magnetization currents associated with the electron spin. The electrons is divided into spin-up and spin-down populations relative to the magnetic field, where the magnetic dipole force acts in opposite directions for the two species. To validate the code, we have studied the wakefield generation by an electromagnetic pulse propagating parallel to an external magnetic field. The properties of the generated wakefield is shown to be in good quantitative agreement with previous theoretical results. Generalizations of the code to account for more quantum effects is discussed
