A String Theory Explanation for Quantum Chaos in the Hadronic Spectrum

TL;DR

This paper uses string theory and holographic models to explain the spectral properties of hadrons, showing compatibility with Wigner's conjecture and linking quantum chaos with string-theoretic descriptions of strong interactions.

Contribution

It provides a string theory-based demonstration of how holographic models can reproduce the spectral characteristics associated with quantum chaos in hadronic spectra.

Findings

Holographic models produce spectra consistent with Wigner's conjecture.

String theory offers a framework to understand quantum chaos in strong interactions.

The results connect classical chaos with quantum spectral properties in hadrons.

Abstract

In the 1950's Wigner and collaborators provided an explanation for the spectrum of hadronic excitations in terms of Random Matrix Theory. In the 1980's it was understood that some hadronic spectral properties were generic to systems whose classical limit is chaotic. We use string theory to demonstrate explicitly how, under very general conditions, recent holographic models of strong interactions have a spectrum compatible with Wigner's conjecture.
