IIB matrix model: Emergent spacetime from the master field

TL;DR

This paper proposes that the large-N master field in the Lorentzian IIB matrix model can generate the points and metric of a classical spacetime, suggesting a mechanism for emergent spacetime from matrix models.

Contribution

It introduces the idea that the master field in the Lorentzian IIB matrix model can produce a classical spacetime structure, advancing understanding of emergent geometry.

Findings

Master field can define points and metric of spacetime

Supports emergent spacetime from matrix models

Provides a new perspective on quantum gravity

Abstract

We argue that the large-$N$ master field of the Lorentzian IIB matrix model can give the points and metric of a classical spacetime.
