Strings as particle arrays

TL;DR

This paper explores how the Polyakov action, fundamental in string theory, can emerge from a system of relativistic particles with harmonic interactions, hinting at a microscopic basis for string theory.

Contribution

It proposes a novel perspective where string theory's Polyakov action arises from a low-energy limit of particle arrays with harmonic interactions.

Findings

Polyakov action derived from particle arrays

Suggests a microscopic foundation for string theory

Connects particle systems to string dynamics

Abstract

These notes discuss the emergence of the Polyakov action from the low-energy limit of an array of relativistic particles with harmonic interactions, which is suggestive of a ``microscopic'' description of string theory.
