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.
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
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
Revealing key structural features hidden in liquids and glasses
A great success of solid state physics comes from the characterization of crystal structures in the reciprocal (wave vector) space. The power of structural characterization in Fourier space
Pore configuration landscape of granular crystallization
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.
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
Persistent homology analysis of deconfinement transition in effective Polyakov-line model
The persistent homology analysis is applied to the effective Polyakov-line model on a rectangular lattice to investigate the confinement–deconfinement nature. The lattice data are mapped onto the


Inorganic glasses, glass-forming liquids and amorphizing solids
We take familiar inorganic oxide glasses and non-oxide glasses and the liquids from which they derive to review the current understanding of their atomic structure, ranging from the local
Local topology of silica networks
Model-building algorithms based on self-assembly according to local rules have been devised, which permit rapid assembly of vertex-sharing tetrahedral network structures. These have been applied to

In his Bakerian Lecture, Bernal (1964) discussed those ideas of restricted irregularity which are physically realized in random packings of equal hard spheres, with particular reference to the
Short range order and stability of a mechanically alloyed Cr25Nb75 glass determined by total scattering and first principles
The atomic environment and stability of an amorphous Cr25Nb75 alloy was studied on the basis of average atomic coordination, average cluster number density as well as cluster radial distribution of

A continuous random network model of amorphous silicon, subject to periodic boundary conditions, is partitioned into cells bounded by irreducible rings. An algorithm has been developed to find the
Ring Configurations in a Random Network Model of Vitreous Silica
THE properties of liquids and glasses may, for many purposes, be classed together. Both lack the extensive regularly repeating groups of atoms that characterize crystalline arrays. X-ray diffraction
Intermediate-range order in permanently densified vitreous SiO2: A neutron-diffraction and molecular-dynamics study.
The structure of pressure-densified vitreous SiO{sub 2} has been investigated using neutron-diffraction and molecular-dynamics techniques and shows substantial changes in the first sharp diffraction peak (FSDP): an indication of modification in the intermediate-range order.
