Numerical simulations of liquids with amorphous boundary conditions

TL;DR

This paper discusses the use of amorphous boundary conditions in simulations to better understand disordered liquids, revealing correlation lengths not accessible through traditional methods.

Contribution

It clarifies the concept of ABCs, explores their connection with point-to-set correlations, and summarizes recent findings using this approach.

Findings

ABCs help measure non-traditional correlation lengths

They provide insights into the dynamics of disordered systems

Recent results demonstrate the effectiveness of ABCs in studying liquids

Abstract

It has recently become clear that simulations under amorphpous boundary conditions (ABCs) can provide valuable information on the dynamics and thermodynamics of disordered systems with no obvious ordered parameter. In particular, they allow to detect a correlation length that is not measurable with standard correlation functions. Here we explain what exactly is meant by ABCs, discuss their relation with point-to-set correlations and briefly describe some recent results obtained with this technique.
