Poisson spot and wave scattering of scalar fields by conformal anomaly black holes: probing the near-horizon geometry
Zeming Zhuang, Hongsheng Zhang, Zong-Kuan Guo +1
We investigate the scattering and diffraction of scalar plane waves by static conformal anomaly black holes. We determine the truncation requirements for the partial-wave series (P…
Second-order multipole response of two nearby incoherent sources in wave-optical imaging of a Schwarzschild black hole
Wenfu Cao, Hongsheng Zhang, Zong-Kuan Guo +1
We study wave-optical imaging of two nearby, mutually incoherent point sources by a Schwarzschild black hole. Using the spherical-harmonic addition theorem, we construct partial-wa…
Quasinormal modes of Schwarzschild--AdS black holes with a near-horizon reflective surface
Libo Xie, Liang-Bi Wu, Yu-Sen Zhou +3
We investigate the scalar quasinormal mode (QNM) spectrum of Schwarzschild-AdS black holes with a partially reflective surface placed near the event horizon. The corresponding QNM…
The (in)stability on total transmission modes with small bumps
Xi-Ning Dong, Liang-Bi Wu, Yu-Sen Zhou +1
Total transmission modes (TTMs) are a class of reflectionless solutions to black hole perturbation equations, closely related to quasinormal modes (QNMs), and can exhibit significa…
Axion Inflation from Heavy-Fermion One-Loop Effects
Kai-Ge Zhang, Jian-Feng He, Chengjie Fu +1
We derive a one-loop effective description of axion inflation by integrating out a heavy Dirac fermion with an inflaton-dependent complex mass undergoing a smooth localized thresho…
