# Further evidence that the transition of 4D dynamical triangulation is 1st order

## TL;DR

This paper provides strong evidence that the phase transition in 4D dynamical triangulation models of quantum gravity is first order, based on analysis at large volume showing a clear double peak in the action histogram.

## Contribution

It confirms the first-order nature of the phase transition in 4D dynamical triangulation quantum gravity models through large-volume simulations.

## Key findings

- Double peak histogram of the action at volume 64,000 four-simplices
- Evidence supporting first-order phase transition
- Contradicts previous beliefs about the transition nature

## Abstract

We confirm recent claims that, contrary to what was generally believed, the phase transition of the dynamical triangulation model of four-dimensional quantum gravity is of first order. We have looked at this at a volume of 64,000 four-simplices, where the evidence in the form of a double peak histogram of the action is quite clear.
