论文摘要
在这项工作中，我们获得了Kerr Black Hole周围巨大标量的准状态。 在Kerr黑洞周围传播的巨大标量通过诱捕井或微小的井诱导远区电位，这会产生共振的峰值或远处的结合状态。前者代表超级不稳定性，而后者可以通过正$ω_i$容纳超级不稳定性。如果标量的能量在微小的井周围确实进行了量化，则可以用类似氢的结合状态表示超轻质玻色子，从而导致重力原子融合了超级不稳定性。如果外界外没有井，则其远区波函数代表纯粹的绑定状态，没有节点。最后，我们区分了超级不稳定性和稳定性。
In this work, we obtain quasibound states of a massive scalar around the Kerr black hole. A massive scalar propagating around the Kerr black hole induces the far-region potential with either a trapping well or a tiny well, which produces a peak of resonance or a bound state in the far-region. The former represents superradiant instability, while the latter could accommodate superradiant instability via a positive $ω_I$. If the scalar's energy is really quantized around a tiny well, an ultralight boson could be expressed in terms of a hydrogen-like bound state, leading to a gravitational atom when incorporating superradiant instability. If there are no wells outside the outer horizon, their far-region wave functions represent purely bound state without node. Finally, we discriminate between superradiant instability and stability.
