# Spectroscopy of Stringy Black Hole

## TL;DR

This paper uses Maggiore's method to analyze the quantization of entropy and area spectra of Garfinkle-Horowitz-Strominger black holes, finding that both spectra are equally spaced and independent of black hole parameters.

## Contribution

It applies the resonance mode analysis with scalar waves to derive parameter-independent, equally spaced entropy and area spectra for GHS black holes.

## Key findings

- Entropy and area spectra are equally spaced.
- Spectra are independent of black hole parameters.
- Resonance modes are computed using high azimuthal quantum number scalar waves.

## Abstract

The Maggiore's method, which evaluates the transition frequency that appears in the adiabatic invariant from the highly damped modes, is used to investigate the entropy/area spectra of the Garfinkle-Horowitz-Strominger black hole (GHS-BH). We compute the resonance modes of the GHS-BH by using the confined scalar waves having high azimuthal quantum number. Although the area and entropy are characterized by the GHS-BH parameters, their quantizations are shown to be independent of those parameters. However, both spectra are equally spaced.
