# Quasinormal modes of supersymmetric microstate geometries from the D1-D5 CFT

## TL;DR

This paper analyzes the quasinormal modes of supersymmetric microstate geometries, demonstrating that their spectrum matches D1-D5 CFT predictions and revealing the nature of these modes as slow leakage from the AdS throat.

## Contribution

It provides a detailed computation of quasinormal modes in microstate geometries and confirms their correspondence with D1-D5 CFT spectrum in certain parameter ranges.

## Key findings

- Spectrum matches D1-D5 CFT analysis for large AdS regions.
- Identifies slow decay modes as leakage from AdS throat.
- Provides detailed wavefunction analysis of quasinormal modes.

## Abstract

We revisit the study of the probe scalar quasinormal modes of a class of three-charge supersymmetric microstate geometries. We compute the real and imaginary parts of the quasinormal modes and show that in the parameter range when the geometries have large AdS region, the spectrum is precisely reproduced from a D1-D5 orbifold CFT analysis. The spectrum includes the slow decaying modes pointed out by Eperon, Reall, and Santos. We analyse in detail the nature of the quasinormal modes by studying the scalar wavefunction. We show that these modes correspond to slow leakage of excitation from AdS throat to infinity.
