Schwarzschild black branes from unstable D-branes

TL;DR

This paper demonstrates how large collections of meta-stable Dp-branes can model Schwarzschild black branes, linking open and closed string descriptions and analyzing horizon properties and internal regions.

Contribution

It generalizes previous models by connecting meta-stable D-brane systems to Schwarzschild black branes in both open and closed string frameworks.

Findings

Identification of horizon size in D-brane systems

Relation between open/closed strings and black brane physics

Inside horizon effects dominated by massive closed strings

Abstract

We study systems with a large number of meta-stable Dp-branes, and show that they describe Schwarzschild and Schwarzschild-like black branes, generalizing the results of Danielsson, Guijosa and Kruczenski. The systems are considered in both the open and closed string pictures. We identify the horizon size and its relation to the physics of open and closed strings. From the closed string perspective the region inside the horizon is where the effects of massive closed strings become important.
