Ten Dimensional Black Hole and the D0-brane Threshold Bound State

TL;DR

This paper explores ten-dimensional black holes composed of D0-branes in a strong coupling regime, proposing they are excitations of a threshold bound state, with entropy and geometric properties aligning with classical predictions.

Contribution

It introduces a novel interpretation of D0-brane black holes as excitations over a threshold bound state, connecting entropy formulas with wave function scaling.

Findings

Horizon radius and mass gap match classical geometry predictions

Entropy formula predicts scaling behavior of the bound state wave function

Black holes can be understood without 11D geometry in strong coupling regime

Abstract

We discuss the ten dimensional black holes made of D0-branes in the regime where the effective coupling is large, and yet the 11D geometry is unimportant. We suggest that these black holes can be interpreted as excitations over the threshold bound state. Thus, the entropy formula for the former is used to predict a scaling region of the wave function of the latter. The horizon radius and the mass gap predicted in this picture agree with the formulas derived from the classical geometry.
