中微子流作用下事件视界的稳定性:经典图象

Stability of event horizons against neutrino flux: The classical picture

Koray Duztas

摘要:

有人声称宇宙审查猜想可以被中微子的量子隧穿所违背,尽管它得到了经典论点的有力支持。本文研究了极端Kerr黑洞与无质量Dirac场(即中微子场)的经典相互作用.通过计算费米子场的能量动量张量和时空的Killing矢量所施加的通量积分,证明了这种相互作用确实可以破坏黑洞的事件视界,使之成为裸奇点.经典过程导致了一个更普遍的违反宇宙审查猜想相比,量子隧穿过程发生的概率很低。可以用来摧毁黑洞的试验中微子场的频率范围,被证明是玻色子场的超辐射范围。我们评述了逆反应和量子效应。我们认为,中微子场对黑洞的破坏不能通过自作用力效应来解决,这与涉及测试体和玻色子场的类似尝试不同。

英文摘要:

It has been claimed that cosmic censorship conjecture can be violated by quantum tunnelling of neutrinos, though it is strongly supported by classical arguments. We consider the classical interaction of an extremal Kerr black hole with a test massless Dirac field, i.e. a "neutrino field". Evaluating the flux integrals imposed by the energy momentum tensor for fermionic fields and the Killing vectors of the space-time, we prove that this interaction can indeed destroy the event horizon of the black hole and convert it to a naked singularity. The classical process leads to a more generic violation of cosmic censorship conjecture compared to quantum tunnelling processes which occur with a low probability. The range of frequencies of the test neutrino field that can be used to destroy the black hole turns out to be the superradiant range for bosonic fields. We comment on back reaction and quantum effects. We argue that the destruction of black holes by neutrino fields cannot be fixed by self-force effects unlike similar attempts involving test bodies and bosonic fields.
