Comparison of low amplitude oscillatory shear in experimental and computational studies of model foams
Micah Lundberg, Kapilanjan Krishan, Ning Xu +2
A fundamental difference between fluids and solids is their response to applied shear. Solids possess static shear moduli, while fluids do not. Complex fluids such as foams display…
Energy transport in jammed sphere packings
Ning Xu, Vincenzo Vitelli, Matthieu Wyart +2
We calculate the normal modes of vibration in jammed sphere packings to obtain the energy diffusivity, a spectral measure of transport. At the boson peak frequency, we find an Ioff…
Excess Vibrational Modes and the Boson Peak in Model Glasses
Ning Xu, Matthieu Wyart, Andrea J. Liu +1
The excess low-frequency normal modes for two widely-used models of glasses were studied at zero temperature. The onset frequencies for the anomalous modes for both systems agree w…
