Nature of Structural Transformations in the B2O3 Glass under High Pressure
V. V. Brazhkin, Y. Katayama, K. Trachenko +7
We report the results of the X-ray diffraction study of B2O3 glass in the pressure interval up to 10 GPa in the 300-700 K temperature range, the results of in-situ volumetric measu…
Network rigidity and dynamics of oxides
Kostya Trachenko, Martin T Dove
If a hierarchy of interatomic interactions exists in a solid, low-frequency modes can be found from viewing this solid as a mechanical network. In this case, the low-frequency mode…
Liquid elasticity length, universal dynamic crossovers and glass transition
K Trachenko, V V Brazhkin
We discuss two main universal dynamic crossovers in a liquid that correspond to relaxation times of 1 ps and 10^{-7}--10^{-6} s. We introduce the concept of liquid elasticity lengt…
Relationship between non-exponentiality of relaxation and relaxation time at the glass transition
K. Trachenko, C. M. Roland, R. Casalini
By analyzing the experimental data for various glass-forming liquids and polymers, we find that non-exponentiality and the relaxation time are uniquely related: i…
The Vogel-Fulcher-Tamman law in the elastic theory of glass transition
Kostya Trachenko
We propose that the origin of the Vogel-Fulcher-Tammann law is the increase of the range of elastic interaction between local relaxation events in a liquid. In this picture, we dis…
Slow dynamics and stress relaxation in a liquid as an elastic medium
K Trachenko
We propose a new framework to discuss the transition from exponential relaxation in a liquid to the regime of slow dynamics. For the purposes of stress relaxation, we show that a l…
