Sound attenuation in finite-temperature stable glasses
Lijin Wang, Elijah Flenner, Grzegorz Szamel
The temperature dependence of the thermal conductivity of amorphous solids is markedly different from that of their crystalline counterparts, but exhibits universal behaviour. Soun…
Energy Transport in Glasses
Elijah Flenner, Lijin Wang, Grzegorz Szamel
The temperature dependence of the thermal conductivity is linked to the nature of the energy transport at a frequency omega, which is quantified by thermal diffusivity d(omega). He…
Sound attenuation in stable glasses
Lijin Wang, Ludovic Berthier, Elijah Flenner +2
Understanding the difference between universal low-temperature properties of amorphous and crystalline solids requires an explanation of the stronger damping of long-wavelength pho…
Low-frequency vibrational modes of stable glasses
Lijin Wang, Andrea Ninarello, Pengfei Guan +3
We numerically study the evolution of the vibrational density of states of zero-temperature glasses when their kinetic stability is varied over an extremely broad range, ran…
Non-monotonic pressure dependence of the dynamics of soft glass-formers at high compressions
Lijin Wang, Yiheng Duan, Ning Xu
In molecular dynamics simulations of soft glass-formers interacting via repulsions, we find that the glass transition temperature, dynamical heterogeneity, and glass fragility reac…
