# Signatures of the Mott transition in the antiferromagnetic state of the two-dimensional Hubbard model

## TL;DR

This paper investigates how the Mott transition influences the antiferromagnetic state in the 2D Hubbard model, revealing sharp crossovers in magnetic correlations and local density of states linked to the normal phase's Mott transition.

## Contribution

It demonstrates the impact of the normal phase's Mott transition on the antiferromagnetic properties within the 2D Hubbard model using advanced computational methods.

## Key findings

- Sharp crossovers in antiferromagnetic correlations
- Changes in local density of states at transition points
- Normal phase Mott transition controls these crossovers

## Abstract

The properties of a phase with large correlation length can be strongly influenced by the underlying normal phase. We illustrate this by studying the half-filled two-dimensional Hubbard model using cellular dynamical mean-field theory with continuous-time quantum Monte Carlo. Sharp crossovers in the mechanism that favors antiferromagnetic correlations and in the corresponding local density of states are observed. These crossovers occur at values of the interaction strength $U$ and temperature $T$ that are controlled by the underlying normal-state Mott transition.
