The role of local structure in dynamical arrest

CP Royall, SR Williams - Physics Reports, 2015 - Elsevier
Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

[HTML][HTML] Liquid–liquid transition and polyamorphism

H Tanaka - The Journal of Chemical Physics, 2020 - pubs.aip.org
Two or more liquid states may exist even for single-component substances, which is known
as liquid polymorphism, and the transition between them is called liquid–liquid transition …

Common microscopic structural origin for water's thermodynamic and dynamic anomalies

R Shi, J Russo, H Tanaka - The Journal of chemical physics, 2018 - pubs.aip.org
Water displays a vast array of unique properties, known as water's anomalies, whose origin
remains subject to hot debate. Our aim in this article is to provide a unified microscopic …

Stretched and compressed exponentials in the relaxation dynamics of a metallic glass-forming melt

The dynamics of glass-forming systems shows a multitude of features that are absent in
normal liquids, such as non-exponential relaxation and a strong temperature-dependence of …

Atomistic study of liquid fragility and spatial heterogeneity of glassy solids in model binary alloys

M Wakeda, T Ichitsubo - NPG Asia Materials, 2023 - nature.com
Fragility is a fundamental property of glass-forming liquids. Here, we evaluated the liquid
fragility and structural and dynamic heterogeneity of glassy solids for four model binary …

Atomic-scale dynamics of a model glass-forming metallic liquid: Dynamical crossover, dynamical decoupling, and dynamical clustering

A Jaiswal, T Egami, Y Zhang - Physical Review B, 2015 - APS
The phase behavior of multicomponent metallic liquids is exceedingly complex because of
