Several mean-field theories predict that the Hessian matrix of amorphous solids converges to the Wishart matrix in the limit of large spatial dimensions. Motivated by these results, we calculate here the density of states of random packing of harmonic spheres by mapping the Hessian of the original system to the Wishart matrix. We compare our result with that of previous numerical simulations...

How do soft granular materials (or dense amorphous systems) respond to
externally applied deformations at different rates – from fast to slow
to very slow – and for different system sizes? This long-standing
question was intensively studied for shear deformation modes, but only
more recently also for isotropic deformations, like
compression-decompression cycles [1,2]. For moderate strain...
