Maxwell Theory from Matrix Model

TL;DR

This paper proposes a method to derive Maxwell theory from the IIB matrix model by relating different dimensional theories through specific background limits, and explores the origin of electric-magnetic duality within this framework.

Contribution

It introduces a novel approach to obtain Maxwell theory from the IIB matrix model using background limits and discusses the duality origin in this context.

Findings

Maxwell theory can be derived from the IIB matrix model via background limits.

Open string bits act as bi-local fields decoupled in certain limits.

Electric-magnetic duality has a matrix model origin.

Abstract

We present a scenario for deriving Maxwell theory from IIB matrix model. Four dimensional spacetime and theories on it relate different dimensional ones by applying appropriate limits of the backgrounds of matrix model. It is understood by looking at open strings bits as bi-local fields on the spacetime, which are decoupled from the bulk in the limits. The origin of electric-magnetic duality is also discussed in matrix model.
