自旋对等离子体中有质动力的贡献

Spin contribution to the ponderomotive force in a plasma

G. Brodin, A. P. Misra, M. Marklund

摘要:

发展了由于电子的内禀自旋而产生的有质动力的概念。一个表达式包含的经典以及自旋诱导有质动力的推导。结果表明,电磁脉冲可以诱导自旋极化等离子体。此外,它表明,对于某些参数,非线性反作用的电磁脉冲的自旋磁化电流可以大于从经典的自由电流。合适的参数值直接测试这种效果。

英文摘要:

The concept of a ponderomotive force due to the intrinsic spin of electrons is developed. An expression containing both the classical as well as the spin-induced ponderomotive force is derived. The results are used to demonstrate that an electromagnetic pulse can induce a spin-polarized plasma. Furthermore, it is shown that for certain parameters, the nonlinear back-reaction on the electromagnetic pulse from the spin magnetization current can be larger than that from the classical free current. Suitable parameter values for a direct test of this effect are presented.
