Isospectrality and configurational entropy as testing tools for bottom-up AdS/QCD

TL;DR

This paper explores how isospectrality and configurational entropy can serve as tools to evaluate and select bottom-up AdS/QCD models, focusing on their spectral properties and stability at zero temperature.

Contribution

It introduces the use of monoparametric isospectral transformations to analyze and constrain softwall-like holographic models based on their decay constants and configurational entropy.

Findings

Isospectral parameter $$ defines a viable model window.

Configurable entropy varies with isospectral transformations.

Models can be selected based on spectral and entropy criteria.

Abstract

This work discusses the connection between isospectrality and configurational entropy in holographic bottom-up models. We analyze the effect of monoparametric isospectral transformation in holographic decay constants and configurational entropy for a set of softwall-like models at zero temperature. We conclude that the isospectral parameter $\lambda$ defines a window of possible holographic models suitable to describe spectroscopy.
