磁化Ernst-Schwarzschild时空中中性粒子和带电粒子的混沌运动

Chaotic motion of neutral and charged particles in the magnetized Ernst-Schwarzschild spacetime

Dan Li, Xin Wu

摘要:

在均匀磁场中,史瓦西黑洞周围的中性粒子没有电磁力的相互作用,但它们的运动可能是混沌的。这种混沌行为是由于磁场的引力效应导致磁化的恩斯特-史瓦西时空几何的不可积性而引起的。事实上,在适当的情况下,混沌通常随着能量或磁场的增加而增强。当这些测试粒子带有电荷时,电磁力也包括在内。结果,电磁力对加强或削弱由磁场的引力效应引起的混沌程度具有影响。

英文摘要:

Neutral test particles around a Schwarzschild black hole immersed in an external uniform magnetic field have no interactions of electromagnetic forces, but their motions can be chaotic. This chaotic behavior is induced owing to the gravitational effect of the magnetic field leading to the nonintegrability of the magnetized Ernst-Schwarzschild spacetime geometry. In fact, chaos is strengthened typically with an increase of the energy or the magnetic field under appropriate circumstances. When these test particles have charges, the electromagnetic forces are included. As a result, the electromagnetic forces have an effect on strengthening or weakening the extent of chaos caused by the gravitational effect of the magnetic field.
