大质量费米子反常磁矩驱动的磁场不稳定性及与背景物质的电弱相互作用

Magnetic field instability driven by anomalous magnetic moments of massive fermions and electroweak interaction with background matter

Maxim Dvornikov

摘要:

结果表明,当粒子具有反常磁矩并与背景物质发生电弱相互作用时,可以激发出大质量费米子沿外磁场的电流。该电流是根据外场中狄拉克方程的精确解计算的。结果表明,如果在麦克斯韦方程组中考虑该电流,则磁场变得不稳定。考虑到一个特定的情况下,简并电子气,这可以在中子星中发现,它揭示了种子磁场可以显着增强。本文还讨论了这些结果在天体物理学中的应用。

英文摘要:

It is shown that the electric current of massive fermions along the external magnetic field can be excited in the case when particles possess anomalous magnetic moments and electroweakly interact with background matter. This current is calculated on the basis of the exact solution of the Dirac equation in the external fields. It is shown that the magnetic field becomes unstable if this current is taken into account in the Maxwell equations. Considering a particular case of a degenerate electron gas, which can be found in a neutron star, it is revealed that the seed magnetic field can be significantly enhanced. The application of the results to astrophysics is also discussed.
