On the ratio between longitudinal and transverse Ioffe-Regel frequencies in glasses
Licun Fu, Mingyu Zhu, Xinyu Chang +1
The temperature dependence of thermal conductivity in glasses differs characteristically from that in crystals, and is largely controlled by how sound waves are damped. The Ioffe-R…
Scaling of the Non-Phononic Spectrum of Two-Dimensional Glasses
Lijin Wang, Grzegorz Szamel, Elijah Flenner
Low-frequency vibrational harmonic modes of glasses are frequently used to understand their universal low-temperature properties. One well studied feature is the excess low-frequen…
Scaling of the Non-Phononic Spectrum of Two-Dimensional Glasses
Lijin Wang, Grzegorz Szamel, Elijah Flenner
The scaling of the non-phononic spectrum for 2D systems has been recently debated. Here we provide evidence that the non-phononic spectrum where …
Density of States below the First Sound Mode in 3D Glasses
Lijin Wang, Licun Fu, Yunhuan Nie
Glasses feature universally low-frequency excess vibrational modes beyond Debye prediction, which could help rationalize, e.g., the glasses' unusual temperature dependence of therm…
Low-frequency excess vibrational modes in two-dimensional glasses
Lijin Wang, Grzegorz Szamel, Elijah Flenner
Glasses possess more low-frequency vibrational modes than predicted by Debye theory. These excess modes are crucial for the understanding the low temperature thermal and mechanical…
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…
Revealing the Link between Structural Relaxation and Dynamic Heterogeneity in Glass-Forming Liquids
Lijin Wang, Ning Xu, W. H. Wang +1
Despite the use of glasses for thousands of years, the nature of the glass transition is still mysterious. On approaching the glass transition, the growth of dynamic heterogeneity…
The correlation between fragility, density and atomic interaction in glass-forming liquids
Lijin Wang, Pengfei Guan, W. H. Wang
The fragility, that controls the temperature-dependent viscous properties of liquids as the glass transition is approached, in various glass-forming liquids with different atomic i…
Disordered Solids Without Well-Defined Transverse Phonons: The Nature of Hard Sphere Glasses
Xipeng Wang, Wen Zheng, Lijin Wang +1
We probe the Ioffe-Regel limits of glasses with repulsions near the zero-temperature jamming transition by measuring the dynamical structure factors. At zero temperature, the trans…
Probing the glass transition from structural and vibrational properties of zero-temperature glasses
Lijin Wang, Ning Xu
We find that the density dependence of the glass transition temperature of Lennard-Jones (LJ) and Weeks-Chandler-Andersen (WCA) systems can be predicted from properties of the zero…
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…
Critical scalings and jamming in thermal colloidal systems
Lijin Wang, Ning Xu
During the jamming of thermal colloids, the first peak of the pair distribution function shows a maximum height . We find that is accompanied by sign…
