The Dynamical Instability of Rotating Boson Stars
Kai-Dong Zhou, Shou-Shan Bao, Jian Deng +1
We investigate the dynamical instability of rotating boson stars described by the Gross--Pitaevskii--Poisson equations with contact self-interactions. Through three-dimensional sim…
Local Group Velocity Distribution inside Superradiant Condensates
Yin-Da Guo, Kai-Dong Zhou, Shou-Shan Bao +1
Superradiance enables scalar fields to extract energy and angular momentum from a rotating black hole (BH), leading to the formation of a BH-condensate system. Previous studies mai…
Light Axion-Like Particles at Future Lepton Colliders
Shou-shan Bao, Yang Ma, Yongcheng Wu +2
Axion-like particles (ALPs) are well-motivated extensions of the Standard Model (SM) that appear in many new physics scenarios, with masses spanning a broad range. In this work, we…
Superradiant dark matter production from primordial black holes: Impact of multiple modes and gravitational wave emission
Nayun Jia, Shou-Shan Bao, Chen Zhang +2
Rotating primordial black holes (PBHs) in the early universe can emit particles through superradiance, a process particularly efficient when the particle's Compton wavelength is co…
Effect of accretion on scalar superradiant instability
Yin-Da Guo, Shou-Shan Bao, Tianjun Li +1
Superradiance can lead to the formation of a black hole (BH) condensate system. We thoroughly investigate the accretion effect on the evolution of this system, and the gravitationa…
Next-to-leading order corrections to scalar perturbations of Kerr-anti-de Sitter black holes
Xiang-hao Chu, Yi-qing Chu, Shou-shan Bao +1
The small Kerr-anti-de Sitter black hole demonstrates instability due to the superradiance of either a massive or massless scalar field. Previous leading-order approximations of th…
Evolution and detection of vector superradiant instabilities
Yin-Da Guo, Nayun Jia, Shou-Shan Bao +2
Ultralight vectors can extract energy and angular momentum from a Kerr black hole (BH) due to superradiant instability, resulting in the formation of a BH-condensate system. In thi…
Constraining axion-gluon coupling in monohadron processes
Shou-shan Bao, Wenhai Gao, Hong Zhang +1
The axion-gluon coupling can be constrained directly through hard exclusive processes at the LHC. Specifically, we study the associated production of a long-lived axion with a $ρ^0…
