Two-dimensional superstrings and the supersymmetric matrix model

TL;DR

This paper provides evidence that a supersymmetric matrix model describes the world-line theory of unstable D-particles in two-dimensional superstring theory, hinting at a holographic duality with a black hole geometry.

Contribution

It identifies a specific matrix model as the world-line theory for D-particles in 2D superstring theory, suggesting a holographic correspondence with black hole backgrounds.

Findings

Matrix model corresponds to D-particles in 2D superstring theory

Supports holographic duality with 2D black hole geometry

Provides a new perspective on non-perturbative string dynamics

Abstract

We present evidence that the supersymmetric matrix model of Marinari and Parisi represents the world-line theory of N unstable D-particles in type II superstring theory in two dimensions. This identification suggests that the matrix model gives a holographic description of superstrings in a two-dimensional black hole geometry.
