Long-wavelength structural anomalies in jammed systems
Long-wavelength structural anomalies in jammed systems
The structural properties of static, jammed packings of monodisperse spheres in the vicinity of the jamming transition are investigated using large-scale computer simulations. At small wave number $k$, we argue that the anomalous behavior in the static structure factor, $S(k)\ensuremath{\sim}k$, is consequential of an excess of low-frequency, collective excitations seen …
