Self-interacting gravitational atoms in the strong-gravity regime
Self-interacting gravitational atoms in the strong-gravity regime
Abstract We numerically investigate free and self-interacting ultralight scalar fields around black holes in General Relativity. We focus on complex scalar fields Φ whose self-interactions are described by the quartic potential V ∝ λ |Φ| 4 , and ignore the black hole spin in order to disentangle the effects of …
