# Chaos in the Fishnet

## TL;DR

This paper analyzes chaos in non-unitary fishnet theories with mass terms by computing out-of-time-ordered correlators, revealing violations of the chaos bound at strong coupling and comparing with six-dimensional honeycomb theories.

## Contribution

It provides the first calculation of OTOCs in mass-deformed fishnet theories and demonstrates chaos and bound violations in these models.

## Key findings

- Fishnet theories exhibit chaos with a calculable growth exponent.
- At strong coupling, the growth exponent exceeds the chaos bound.
- Similar chaotic behavior is observed in six-dimensional honeycomb theories.

## Abstract

We consider the computation of out-of-time-ordered correlators (OTOCs) in the fishnet theories, with a mass term added. These fields theories are not unitary. We compute the growth exponent, in the planar limit, at any value of the coupling and show that the model exhibits chaos. At strong coupling the growth exponent violates the Maldacena-Shenker-Stanford bound. We also consider the mass deformed versions of the six dimensional honeycomb theories, which can also be solved in the planar limit. The honeycomb theory shows a very similar behavior to that exhibited by the fishnet theory.
