Description
We consider the geodesics and the profiles of scalar normal and quasinormal modes in supergravity backgrounds with 1/2 BPS, 1/4 BPS and 1/16 BPS supersymmetry (bubbling geometries and D1-D5-P microstates and black holes). We show that the (quasi)normal modes show progressively stronger chaos in the sense of the Berry random wave conjecture as we reduce the supersymmetry and approach the black hole limit. We interpret this finding in the context of the recent works on BPS chaos in holographic CFTs. We further show how the dynamics of sets of geodesics also approaches the black hole behavior as we reduce supersymmetry. We comment the consequences of our findings for the idea of ensemble averaging in black hole solutions.
