Tidal resonances for fuzzballs

TL;DR

This paper investigates the tidal response of fuzzball geometries, revealing resonant peaks linked to metastable bound states, contrasting black hole behavior.

Contribution

It introduces a detailed analysis of tidal resonances in fuzzball geometries, combining semi-analytical and numerical methods to identify resonant frequencies.

Findings

Fuzzball geometries exhibit resonant peaks in tidal interactions.

Resonant frequencies correspond to metastable bound states.

Distinct tidal response compared to traditional black holes.

Abstract

We study the gravitational tidal response of D1D5, Top Star and (1,0,n) strata horizonless geometries. We find that the tidal interactions in fuzzball geometries, unlike in the case of black holes, exhibits a sequence of resonant peaks associated to the existence of metastable bound states. The spectrum of resonant frequencies is computed by semi-analytical and numerical methods.
