论文摘要
光，基本骨骼场的存在是一种有吸引力的可能性，可以通过黑洞观测来测试。我们研究了由伴侣恒星或黑洞引起的潮汐场的影响，对旋转黑洞周围的超级标量状态状态的演变。对于小型潮汐场，超级“云”通过过渡到激发状态并通过过渡到较高的多物获得新的空间分布，从而建立了新的平衡构型，从而膨胀了新的平衡构型。从数值上，我们确定要实现这一目标的关键潮汐时刻，并与牛顿估计找到良好的一致性。我们表明，潮汐的影响可能与已知的黑洞系统（例如我们银河系中心或Cygnus X-1系统的一个系统）有关。例如，Cygnus X-1的同伴将破坏BH周围可能的标量结构，以使重力耦合大至$Mμ\ SIM \ SIM 2 \ times 10^{ - 3} $。
The existence of light, fundamental bosonic fields is an attractive possibility that can be tested via black hole observations. We study the effect of a tidal field -- caused by a companion star or black hole -- on the evolution of superradiant scalar-field states around spinning black holes. For small tidal fields, the superradiant "cloud" puffs up by transitioning to excited states and acquires a new spatial distribution through transitions to higher multipoles, establishing new equilibrium configurations.For large tidal fields the scalar condensates are disrupted; we determine numerically the critical tidal moments for this to happen and find good agreement with Newtonian estimates. We show that the impact of tides can be relevant for known black-hole systems such as the one at the center of our galaxy or the Cygnus X-1 system. The companion of Cygnus X-1, for example, will disrupt possible scalar structures around the BH for gravitational couplings as large as $Mμ\sim 2\times 10^{-3}$.
