Black hole formation in $c=1$ String Field Theory

TL;DR

This paper explores how black holes can form within the $c=1$ String Field Theory framework, demonstrating that perturbations near a potential barrier can generate black hole geometries, including the exact $D=2$ black hole metric.

Contribution

It proposes a mechanism for black hole formation in $c=1$ String Field Theory and derives the exact $D=2$ black hole metric from perturbations.

Findings

Perturbations near the potential barrier can produce black hole geometries.

The exact $D=2$ black hole metric is derived within the theory.

Black hole formation is linked to energy input and system perturbations.

Abstract

A suggestion on how black holes may appear in Das-Jevicki Collective field theory is given. We study the behaviour of a `test' particle when energy is sent into the system. A perturbation moving near the potential barrier can create a large-distance black hole geometry where the seeming curvature singularity is at the position of the barrier. In the simplest `static' case the exact $D=2$ black hole metric emerges.
