Black hole binaries and light fields: Gravitational molecules

Résumé

We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these states are formally described by the quantum-mechanical Schrödinger 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.
