旋量场与时空对称性

Spinor Fields and Symmetries of the Spacetime

Jianwei Mei

摘要:

在静止黑洞的背景中,特定旋量场的“守恒流”总是接近视界上的零Killing矢量。而且,当黑洞是渐近平坦的,当坐标系是渐近静态的,那么同样的电流也会在空间无穷远处接近时间Killing矢量。我们用不同的黑洞解检验了这些结果,没有发现例外。旋量场只需要满足一个非常一般和简单的约束。

英文摘要:

In the background of a stationary black hole, the "conserved current" of a particular spinor field always approaches the null Killing vector on the horizon. What's more, when the black hole is asymptotically flat and when the coordinate system is asymptotically static, then the same current also approaches the time Killing vector at the spatial infinity. We test these results against various black hole solutions and no exception is found. The spinor field only needs to satisfy a very general and simple constraint.
