Orientational Glass Transition

TL;DR

This paper investigates the static properties of orientational glasses using a replica theory framework, applying a generalized model to dipolar and quadrupolar glasses, and compares numerical results across different models.

Contribution

It introduces a general replica-based model for orientational glasses, including dipolar and quadrupolar types, with numerical analysis and model comparisons.

Findings

Numerical results for the <100> quadrupolar glass are presented.

Comparison with Ising and <111> orientational glass models shows differences.

The model provides insights into the static behavior of orientational glasses.

Abstract

The static behavior of orientational glasses is discussed in terms of a replica theory based on the infinite range random bond--random field model. A general version of the model applicable to dipolar and quadrupolar glasses is presented using a symmetry-adapted representation for the order parameter fields. Numerical results for the $<100>$ quadrupolar glass are obtained and compared with the Ising and $<111>$ orientational glass models.
