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…

Phase Transition and Critical Phenomena of Charged Einstein-Maxwell-Scalar Black Holes
Zeming Zhuang, Kun Meng, Hongsheng Zhang
We study the phase transition and critical phenomenon of charged black holes in Einstein-Maxwell-scalar (EMs) theory. Through comprehensive analysis of thermodynamic behaviors mani…
