# Recent results in Euclidean dynamical triangulations

## TL;DR

This paper investigates Euclidean dynamical triangulations (EDT) as a lattice gravity approach, showing evidence of recovering semi-classical 4D geometries and a short-distance spectral dimension of 3/2, aligning with other quantum gravity models.

## Contribution

It demonstrates that with a specific measure tuning, EDT can produce semi-classical 4D geometries and matches spectral dimension results from CDT.

## Key findings

- Evidence of 4D semi-classical geometries at long distances
- Spectral dimension at short distances is approximately 3/2
- Fine-tuning the measure term is crucial for continuum limit

## Abstract

We study a formulation of lattice gravity defined via Euclidean dynamical triangulations (EDT). After fine-tuning a non-trivial local measure term we find evidence that four-dimensional, semi-classical geometries are recovered at long distance scales in the continuum limit. Furthermore, we find that the spectral dimension at short distance scales is consistent with 3/2, a value that is also observed in the causal dynamical triangulation (CDT) approach to quantum gravity.
