Horizon-Scale Corrections to Black Hole Geometry from a Conserved Quantum Atmosphere
Kashif Ammar Yasir
Black holes are usually described either as classical geometries on which quantum fields propagate or as objects whose complete quantum description lies beyond semiclassical gravit…
Black Hole Horizon Fluctuations from Unruh Quantum Noise
Kashif Ammar Yasir
The mean Hawking flux does not determine how quantum stress fluctuations perturb a black-hole geometry. That information resides in field correlations, including vacuum contributio…
Colored-Noise-Induced Horizon Fluctuations Near a Double Root in an Effective Black-Hole Geometry
Kashif Ammar Yasir
Stress-tensor fluctuations carry information that is absent from the mean semiclassical Einstein equation, but their observable effect depends as much on the response of the geomet…
