Properties of the Z(3) Interface in (2+1)-D SU(3) Gauge Theory

TL;DR

This paper investigates the properties of Z(3) interfaces in (2+1)-dimensional SU(3) gauge theory, measuring interface tension at high temperatures and analyzing fluctuations near the critical point, comparing results with theoretical models.

Contribution

It provides the first detailed measurement of interface tension in (2+1)D SU(3) gauge theory and compares interface fluctuations to scalar field models.

Findings

Interface tension agrees with perturbative predictions at high temperatures.

Interface fluctuations near the critical temperature match scalar field theory behavior.

The study enhances understanding of phase interfaces in lower-dimensional gauge theories.

Abstract

A study is made of some properties of this interface in the SU(3) pure gauge theory in 2+1 dimensions. At high temperatures, the interface tension is measured and shows agreement with the perturbative prediction. Near the critical temperature, the behaviour of the interface is examined, and its fluctuations compared to a scalar field theory model.
