Proliferation of non-linear excitations in the piecewise-linear perceptron
Antonio Sclocchi, Pierfrancesco Urbani
We investigate the properties of local minima of the energy landscape of a continuous non-convex optimization problem, the spherical perceptron with piecewise linear cost function…
Surfing on minima of isostatic landscapes: avalanches and unjamming transition
Silvio Franz, Antonio Sclocchi, Pierfrancesco Urbani
Recently, we showed that optimization problems, both in infinite as well as in finite dimensions, for continuous variables and soft excluded volume constraints, can display entire…
Critical energy landscape of linear soft spheres
Silvio Franz, Antonio Sclocchi, Pierfrancesco Urbani
We show that soft spheres interacting with a linear ramp potential when overcompressed beyond the jamming point fall in an amorphous solid phase which is critical, mechanically mar…
