Quiver Mechanics for Deconstructed Matrix String

TL;DR

This paper introduces a quiver model of matrix quantum mechanics with 8 supercharges that deconstructs the Matrix String Theory worldsheet, avoids fermion doubling, and enhances supersymmetry in the continuum limit.

Contribution

It presents a novel quiver-based deconstruction approach that links target space compactification with worldsheet construction, improving upon previous models.

Findings

Model evades fermion doubling problem

Enhances supersymmetry to sixteen in the continuum limit

Establishes duality between target space compactification and worldsheet deconstruction

Abstract

In this paper we propose a quiver model of matrix quantum mechanics with 8 supercharges which, on a Higgs branch, deconstructs the worldsheet of Matrix String Theory. This discrete model evades the fermion doubling problem and, in the continuum limit, enhances the number of supersymmetries to sixteen. Our model is motivated by orbifolding the Matrix Model, and the deconstruction {\it ansatz} exhibits a duality between target space compactification and worldsheet deconstruction.
