Spin Stiffness of Stacked Triangular Antiferromagnets

TL;DR

This paper investigates the spin stiffness in stacked triangular antiferromagnets using Monte Carlo methods, providing evidence for a continuous phase transition within the chiral universality class.

Contribution

It offers the first Monte Carlo analysis confirming the chiral universality class for the phase transition in stacked triangular antiferromagnets.

Findings

Results support a continuous transition in the chiral universality class.

Monte Carlo methods used include heat bath and broad histogram techniques.

Findings align with theoretical predictions of Kawamura.

Abstract

We study the spin stiffness of stacked triangular antiferromagnets using both heat bath and broad histogram Monte Carlo methods. Our results are consistent with a continuous transition belonging to the chiral universality class first proposed by Kawamura.
