超强磁场物理

Physics in Ultra-Strong Magnetic Fields

Alice K. Harding

摘要:

一些中子星的表面磁场超过了4.4 x 10^{13} G的临界强度,此时电子回旋能量等于其静止质量能量。这些包括高场旋转动力的中子星、X射线暗淡孤立中子星(XDIN)和磁星。在这样的超强场中,物理过程中的量子效应以及仅在这些高场强下发生的额外的奇异量子电动力学过程对发射的辐射具有显著影响。虽然非常强的磁场在中子星内外都起着至关重要的作用,但我将主要回顾在中子星磁层中运行的过程以及它们如何影响观测到的辐射。

英文摘要:

Several populations of neutron stars have surface magnetic fields above the critical strength of 4.4 x 10^{13} G where the electron cyclotron energy equals its rest mass energy. These include high-field rotation-powered pulsars, X-ray dim isolated neutron stars (XDIN), and magnetars. In such ultra-strong fields, quantum effects in physical processes as well as additional exotic Quantum Electrodynamic processes only occurring at these high field strengths have a significant influence on the emitted radiation. Although very strong magnetic fields play a critical role both inside and outside of neutron stars, I will review primarily processes that operate in the neutron star magnetospheres and how they influence the observed radiation.
