存在电荷和磁荷的磁流体力学

Magnetohydrodynamics in Presence of Electric and Magnetic charges

P. S. Bisht, Pushpa, O. P. S. Negi

摘要:

本文从广义的双子电磁场方程出发,讨论了同时带有电荷和磁荷的粒子(即双子)的等离子体磁流体力学(MHD)理论。结果表明,所得系统支持双子的电磁对偶性。由此得到了双子等离子体的频率,并强调了每种离子体的频率随波数k的不同而不同。当k为实数时,只允许那些通常频率大于等离子体频率(即ω>ω_{p})的广义电磁波通过。结果表明,等离子体频率设置的电磁辐射的频率,可以通过等离子体的较低的削减。在此基础上,重新建立了欧姆定律,导出了等离子体振荡方程、磁流体动力学波动方程和双子能量的唯一一致的表达式。

英文摘要:

Starting with the generalized electromagnetic field equations of dyons, we have discussed the theory of magnetohydrodynamics (MHD) of plasma for particles carrying simultaneously the electric and magnetic charges (namely dyons). It is shown that the resultant system supports the electromagnetic duality of dyons. Consequently the frequency of dyonic plasma has been obtained and it is emphasized that there is a different plasma frequency for each species depending on wave number k. For k to be real, only those generalized electromagnetic waves are allowed to pass, for which the usual frequency is greater than the plasma frequency (i.e. ω>ω_{p}). It is shown that the plasma frequency sets the lower cuts for the frequencies of electromagnetic radiation that can pass through a plasma . Accordingly the ohm's law has been reestablished to derive the plasma oscillation equation as well as the magetohydrodynamic wave equation and the energy of dyons in unique and consistent manner.
