Quantum spectrum of tachyonic black holes in a brane-anti-brane system

TL;DR

This paper investigates the quantum spectrum of tachyonic black holes formed in a brane-anti-brane system, revealing how the spectrum depends on tachyonic potential and brane separation, with energy increasing as they come closer.

Contribution

It extends the analysis of black hole quantum spectra to tachyonic black holes in brane-anti-brane systems, highlighting the influence of tachyonic potential and brane separation.

Findings

Spectrum depends on tachyonic potential and separation distance.

Energy increases as branes approach each other.

Black hole spectrum broadens with decreasing separation.

Abstract

Recently, some authors have considered the quantum spectrum of black holes . This consideration is extended to tachyonic black holes in a brane-anti-brane system. In this study, black holes are constructed from two branes which are connected by a tachyonic tube. As the branes come closer to each other, they evolve and make a transition to thermal black branes. It will be shown that the spectrum of these black holes depends on the tachonic potential and the separation distance between the branes. By decreasing the separation distance, more energy emerges and the spectrum of the black hole increases.
