In the Randall-Sundrum scenario, our universe is a 4-dimensional `brane' living in a 5-dimensional bulk spacetime. By studying the scattering of bulk gravity waves, we show that this brane rings with a characteristic set of complex quasinormal frequencies, much like a black hole. To a bulk observer these modes are interpreted as metastable gravity wave bound states, while a brane observer views them as a discrete spectrum of decaying massive gravitons. Potential implications of these scattering resonances are discussed.

  1. Spectral Butterfly Effect and Resilient Ringdown in Thick Braneworlds

    gr-qc 2026-04 unverdicted novelty 6.0

    Thick braneworlds feature fragile quasinormal mode spectra due to a butterfly effect but maintain a resilient early ringdown, keeping the standard gravitational wave fingerprint usable.

    Holographic analysis of scattering off Chamblin-Reall branes shows that for d>1 incident radiation redistributes into reflected, transmitted, and evanescent components, with d=2 yielding diffuse scattering like a tran...

    gr-qc 2026-04 unverdicted novelty 5.0

    In a thick braneworld model with f(T) = T + α T², the parameter α induces brane splitting and alters the decay rates of quasinormal modes, with two numerical methods agreeing on the low-overtone spectrum.
