Modeling the mechanics of amorphous solids at different length scale and time scale

D Rodney, A Tanguy… - Modelling and Simulation …, 2011 - iopscience.iop.org
We review the recent literature on the simulation of the structure and deformation of
amorphous solids, including oxide and metallic glasses. We consider simulations at different …

Universal link between the boson peak and transverse phonons in glass

H Shintani, H Tanaka - Nature materials, 2008 - nature.com
The physical properties of a topologically disordered amorphous material (glass), such as
heat capacity and thermal conductivity, are markedly different from those of its ordered …

Equivalence of the Boson Peak in Glasses to the<? format?> Transverse Acoustic van Hove Singularity in Crystals

AI Chumakov, G Monaco, A Monaco, WA Crichton… - Physical review …, 2011 - APS
We compare the atomic dynamics of the glass to that of the relevant crystal. In the spectra of
inelastic scattering, the boson peak of the glass appears higher than the transverse acoustic …

Heterogeneous shear elasticity of glasses: the origin of the boson peak

A Marruzzo, W Schirmacher, A Fratalocchi… - Scientific reports, 2013 - nature.com
The local elasticity of glasses is known to be inhomogeneous on a microscopic scale
compared to that of crystalline materials. Their vibrational spectrum strongly deviates from …

Role of disorder in the thermodynamics and atomic dynamics of glasses

AI Chumakov, G Monaco, A Fontana, A Bosak… - Physical Review Letters, 2014 - APS
We measured the density of vibrational states (DOS) and the specific heat of various glassy
and crystalline polymorphs of SiO 2. The typical (ambient) glass shows a well-known excess …

Boson peak dynamics of glassy glucose studied by integrated terahertz-band spectroscopy

M Kabeya, T Mori, Y Fujii, A Koreeda, BW Lee, JH Ko… - Physical review B, 2016 - APS
We performed terahertz time-domain spectroscopy, low-frequency Raman scattering, and
Brillouin light scattering on vitreous glucose to investigate the boson peak (BP) dynamics. In …

New understanding of TeO2–ZnO–Na2O ternary glass system

J de Clermont-Gallerande, S Saito, M Colas… - Journal of Alloys and …, 2021 - Elsevier
Thermal, mechanical structural, and optical properties of the 80TeO 2-xZnO-(20-x) Na 2 O
(TZN) system were investigated. The structural study of the glasses showed that in the TZN …

Temperature dependence of spatial nanoheterogeneities of shear modulus in supercooled glycerol

VN Novikov - The Journal of Chemical Physics, 2024 - pubs.aip.org
The boson peak in the terahertz vibrational spectrum carries information about nano-
heterogeneities in the shear modulus in glass formers. Its evolution upon heating or cooling …

Heat transport in model jammed solids

V Vitelli, N Xu, M Wyart, AJ Liu, SR Nagel - Physical Review E—Statistical …, 2010 - APS
We calculate numerically the normal modes of vibrations in three-dimensional jammed
packings of soft spheres as a function of the packing fraction and obtain the energy …

HR MAS NMR, powder XRD and Raman spectroscopy study of inclusion phenomena in βCD nanosponges
