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…
Glass-like Caging with Random Planes
Gilles Bonnet, Patrick Charbonneau, Giampaolo Folena
The richness of the mean-field solution of simple glasses leaves many of its features challenging to interpret. A minimal model that illuminates glass physics the same way the rand…
On weak ergodicity breaking in mean-field spin glasses
Giampaolo Folena, Francesco Zamponi
The weak ergodicity breaking hypothesis postulates that out-of-equilibrium glassy systems lose memory of their initial state despite being unable to reach an equilibrium stationary…
Introduction to the dynamics of disordered systems: equilibrium and gradient descent
Giampaolo Folena, Alessandro Manacorda, Francesco Zamponi
This manuscript contains the lecture notes of the short courses given by one of us (F.Z.) at the summer school "Fundamental Problems in Statistical Physics XV", held in Brunico, It…
Equilibrium Fluctuations in Mean-field Disordered Models
Giampaolo Folena, Giulio Biroli, Patrick Charbonneau +2
Mean-field models of glasses that present a random first order transition exhibit highly non-trivial fluctuations. Building on previous studies that focused on the critical scaling…
Local dynamical heterogeneity in glass formers
Giulio Biroli, Patrick Charbonneau, Giampaolo Folena +2
We study the local dynamical fluctuations in glass-forming models of particles embedded in -dimensional space, in the mean-field limit of . Our analytical calculatio…
Marginal stability of soft anharmonic mean field spin glasses
Giampaolo Folena, Pierfrancesco Urbani
We investigate the properties of the glass phase of a recently introduced spin glass model of soft spins subjected to an anharmonic quartic local potential, which serves as a model…
Gradient descent dynamics in the mixed -spin spherical model: finite size simulation and comparison with mean-field integration
Giampaolo Folena, Silvio Franz, Federico Ricci-Tersenghi
We perform numerical simulations of a long-range spherical spin glass with two and three body interaction terms. We study the gradient descent dynamics and the inherent structures…
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…
