The characterization of the medium-range (MRO) order in amorphous materials and its relation to the short-range order is discussed. A new topological approach to extract a hierarchical structure of amorphous materials is presented, which is robust against small perturbations and allows us to distinguish it from periodic or random configurations. This method is called the persistence diagram (PD) and introduces scales to many-body atomic structures to facilitate size and shape characterization…

Medium-Range Order in Amorphous Ices Revealed by Persistent Homology.
TLDR
The PH-extracted MRO rings successfully reproduce the quantitative features of the first sharp diffraction peaks in the structure factor, hence suitably serving as the origin of experimental MRO signatures in the amorphous ices and supports that PH is an effective tool to identify hidden MRO in amorphously configurations.
Structure and properties of densified silica glass: characterizing the order within disorder
The broken symmetry in the atomic-scale ordering of glassy versus crystalline solids leads to a daunting challenge to provide suitable metrics for describing the order within disorder, especially on…
Hierarchical structures of amorphous solids characterized by persistent homology
TLDR
A unified method using persistence diagrams for studying the geometry of atomic configurations in amorphous solids, which suggests that the PDs provide a unified method that extracts greater depth of geometric information in amortized solids than conventional methods.
Topological descriptor of thermal conductivity in amorphous materials
Quantifying the correlation between the complex structures of amorphous materials and their physical properties has been a longstanding problem in materials science. In amorphous Si, a representative…

Pore configuration landscape of granular crystallization
TLDR
This map encodes new information on the formation process of tetrahedral and octahedral pores, the building blocks of perfect crystals, which reproduce the main changes of the map during crystallization and provide continuous deformation pathways representative of the crystallization dynamics.
Structure of the simple harmonic-repulsive system in liquid and glassy states studied by the triple correlation function.
TLDR
The findings support the view that the development of the orientational correlations in liquids may play a significant role in the liquids' dynamics and that the considerations of the pair distribution function may not be sufficient to understand intuitively all the structural changes that happen with liquids on supercooling.
Adding a novel material to the 2D toolbox
The library of two-dimensional (2D) materials is limited, since only very few compounds remain stable when they consist of only surfaces. Yet, due to their extraordinary properties, the hunt for new…
