Accretion Disk Perturbations and Their Effects on Kerr Black Hole Superradiance and Gravitational Atom Evolution
Ruiheng Li, Zhong-hao Luo, Zehong Wang +1
Kerr black hole (BH) superradiance can form gravitational atoms and produce characteristic gravitational-wave signals, providing a probe of ultralight bosons and dark matter. In re…

Rapid post-merger gravitational-wave signals from magnetic black hole superradiance: novel approach to detect magnetic monopole and ultralight boson
Zhong-Hao Luo, Fa Peng Huang, Pengming Zhang +1
We present an analytic framework showing that a spinning black hole with net magnetic charge exhibits a greatly enhanced superradiant instability against charged scalar fields comp…

Superradiant instability of area quantized Kerr black hole with discrete reflectivity
Zhong-Hao Luo, Yun-Long Zhang
Ultralight bosons can condense to form the so-called bosonic clouds around spinning black holes by superradiance instability. When quantum effects are taken into account, the class…
