Equilibrium in a Reaction Network of Assemblies
Giampaolo Folena, Germán Kruszewski
We study a mean-field reaction network whose species are assemblies built from identical atoms by reversible coagulation and fragmentation. Each assembly is an ordered binary tree,…
Rare Trajectories in a Prototypical Mean-field Disordered Model: Insights into Landscape and Instantons
Patrick Charbonneau, Giampaolo Folena, Enrico M. Malatesta +2
For disordered systems within the random first-order transition (RFOT) universality class, such as structural glasses and certain spin glasses, the role played by activated relaxat…
The geometry of jamming algorithms in the random Lorentz gas
Giampaolo Folena, Patrick Charbonneau, Peter K. Morse +2
Deterministic optimization algorithms unequivocally partition a complex energy landscape in inherent structures (ISs) and their respective basins of attraction. Can these basins be…
Rethinking mean-field glassy dynamics and its relation with the energy landscape: the awkward case of the spherical mixed p-spin model
Giampaolo Folena, Silvio Franz, Federico Ricci-Tersenghi
The spherical p-spin model is not only a fundamental model in statistical mechanics of disordered system, but has recently gained popularity since many hard problems in machine lea…
