标题： Black hole binaries and light fields: Gravitational molecules

摘要： 我们展示了轻标量可以在双星周围形成准束缚态。在非相对论极限下，这些状态形式上由描述单电子异核双原子分子的量子力学薛定谔方程描述。我们对黑洞双星周围的标量场进行了广泛的数值模拟，结果显示标量结构在双星周围凝聚——我们将这些状态称为“引力分子”。我们进一步表明，这些状态可以用微扰的非相对论描述很好地刻画。 显示英文摘要

摘要： We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these states are formally described by the quantum-mechanical Schrodinger equation for a one-electron heteronuclear diatomic molecule. We performed extensive numerical simulations of scalar fields around black hole binaries showing that a scalar structure condenses around the binary -- we dub these states "gravitational molecules". We further show that these are well described by the perturbative, nonrelativistic description.
