Abstract

Motivated by capturing putative quantum effects at the horizon scale, we
model the black hole horizon as a membrane with fluctuations following a
Gaussian profile. By extending the membrane paradigm at the semiclassical
level, we show that the quantum nature of the black hole horizon implies
partially reflective boundary conditions and a frequency-dependent
reflectivity. This generically results into a modified quasi-normal mode
spectrum and the existence of echoes in the postmerger signal. On a similar
note, we derive the horizon boundary condition for a braneworld black hole that
could originate from quantum corrections on the brane. This scenario also leads
to a modified gravitational-wave ringdown. We discuss general implications of
these findings for scenarios predicting quantum corrections at the horizon
scale.
