Quantum quenches in isolated quantum glasses out of equilibrium
S. J. Thomson, P. Urbani, M. Schiro
In this work, we address the question of how a closed quantum system thermalises in the presence of a random external potential. By investigating the quench dynamics of the isolate…
Mean field theory of jamming of nonspherical particles
Harukuni Ikeda, Pierfrancesco Urbani, Francesco Zamponi
Recent computer simulations have uncovered the striking difference between the jamming transition of spherical and non-spherical particles. While systems of spherical particles are…
Critical jammed phase of the linear perceptron
Silvio Franz, Antonio Sclocchi, Pierfrancesco Urbani
Criticality in statistical physics naturally emerges at isolated points in the phase diagram. Jamming of spheres is not an exception: varying density, it is the critical point that…
Can a large packing be assembled from smaller ones?
Daniel Hexner, Pierfrancesco Urbani, Francesco Zamponi
We consider zero temperature packings of soft spheres, that undergo a jamming to unjamming transition as a function of packing fraction. We compare differences in the structure, as…
Passed & Spurious: Descent Algorithms and Local Minima in Spiked Matrix-Tensor Models
Stefano Sarao Mannelli, Florent Krzakala, Pierfrancesco Urbani +1
In this work we analyse quantitatively the interplay between the loss landscape and performance of descent algorithms in a prototypical inference problem, the spiked matrix-tensor…
