本文考虑黑洞时空中量子场的Boulware态和Hartle-Hawking态的定义。史瓦西黑洞上这些态的性质已经被理解了很多年,但是这两个态都没有直接类似于克尔黑洞。我们展示了超辐射模如何在克尔量子态的定义中发挥重要作用。超辐射也存在于静态黑洞时空中,特别是对于Reissner-Nordström黑洞上的带电标量场。我们探讨是否存在类似的Boulware和Hartle-Hawking状态在这种情况下。
We consider the definition of the Boulware and Hartle-Hawking states for quantum fields on black hole space-times. The properties of these states on a Schwarzschild black hole have been understood for many years, but neither of these states has a direct analogue on a Kerr black hole. We show how superradiant modes play an important role in the definition of quantum states on Kerr. Superradiance is also present on static black hole space-times, in particular for a charged scalar field on a Reissner-Nordström black hole. We explore whether analogues of the Boulware and Hartle-Hawking states exist in this situation.
