It is shown that Kerr-Newman black holes can support linear charged scalar fields in their exterior regions. To that end, we solve analytically the Klein-Gordon wave equation for a stationary charged massive scalar field in the background of a near-extremal Kerr-Newman black hole. In particular, we derive a simple analytical formula which describes the physical properties of these stationary bound-state resonances of the charged massive scalar fields in the Kerr-Newman black-hole spacetime.

  1. Stationary scalar clouds around a rotating Kalb-Ramond BTZ black hole

    gr-qc 2026-06 unverdicted novelty 4.0

    Stationary scalar clouds exist around rotating KR BTZ black holes at superradiant threshold ω=mΩ_H, with positive KR parameter allowing nonmonotonic existence lines under Robin boundaries.
