# A note on holographic subregion complexity and QCD phase transition

## TL;DR

This paper explores the relationship between holographic subregion complexity and the QCD phase transition, revealing how meson complexity behavior correlates with phase changes and energy differences.

## Contribution

It introduces a novel analysis connecting meson potential energy, complexity, and phase transition behavior in a holographic QCD model.

## Key findings

- Complexity decreases near the critical point in non-conformal vacuum.
- Less information is needed to specify mesons in non-conformal vacuum despite higher energy.
- A link between meson potential energy and complexity behavior is established.

## Abstract

Using holographic subregion complexity, we study the confinement-deconfinement phase transition of quantum chromodynamics. In the model we consider here, we observe a connection between the potential energy of probe meson and the behavior of its complexity. Moreover, near the critical point, at which the phase transition takes place, our numerical calculations indicate that we need less information to specify a meson in the non-conformal vacuum than in the conformal one, despite the fact that the non-conformal vacuum has larger energy!
