Universal properties of high-frequency spectra in glass formers

TL;DR

This paper explores the unique vibrational spectra of glass formers, explaining their anomalies using euclidean random matrix theory and suggesting experiments at various densities to test these predictions.

Contribution

It introduces a theoretical framework based on euclidean random matrix theory to explain the anomalous vibrational spectra of glass formers.

Findings

Vibrational spectra of glass formers differ from crystals.

Euclidean random matrix theory explains these differences.

Proposes experiments at different densities to validate the theory.

Abstract

The vibrational spectra of glass formers follow different laws with respect to crystals. A rationale for their anomalous behaviour is provided by the euclidean random matrix theory. Experiments on glass formers at different densities might be a suitable route to test the prediction of the theory.
