Electromagnetic Albedo of Quantum Black Holes
Wan Zhen Chua, Niayesh Afshordi
We compute the albedo (or reflectivity) of electromagnetic waves off the electron-positron Hawking plasma that surrounds the horizon of a Quantum Black Hole. We adopt the "modified…
Virasoro hair and entropy for axisymmetric Killing horizons
Lin-Qing Chen, Wan Zhen Chua, Shuwei Liu +2
We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with cen…
Imprints of Schwinger Effect on Primordial Spectra
Wan Zhen Chua, Qianhang Ding, Yi Wang +1
We study the Schwinger effect during inflation and its imprints on the primordial power spectrum and bispectrum. The produced charged particles by Schwinger effect during inflation…
Quantum Standard Clocks in the Primordial Trispectrum
Xingang Chen, Wan Zhen Chua, Yuxun Guo +3
We calculate the primordial trispectrum of curvature perturbation in quasi-single field inflation, with general sound speeds for both the inflaton and the massive scalar. Special a…
