Attenuation of shear sound waves in jammed solids
Attenuation of shear sound waves in jammed solids
We study the attenuation of long-wavelength shear sound waves propagating through model jammed packings of frictionless soft spheres interacting with repulsive springs. The elastic attenuation coefficient, α(ω), of transverse phonons of low frequency, ω, exhibits power law scaling as the packing fraction ϕ is lowered towards ϕc, the critical packing …
