Fragile vs robust Multiple Equilibria phases in generalized Lotka-Volterra model with non-reciprocal interactions
Thomas Louis-Sarrola, Valentina Ros
We investigate the Multiple Equilibria phase of generalized Lotka-Volterra dynamics with random, non-reciprocal interactions. We compute the topological complexity of equilibria, w…
Non-reciprocal interactions and high-dimensional chaos: comparing dynamics and statistics of equilibria in a solvable class of models
Samantha J. Fournier, Alessandro Pacco, Valentina Ros +1
We investigate a model of high-dimensional dynamical variables with all-to-all interactions that are random and non-reciprocal. We characterize its phase diagram and show that the…
High-dimensional random landscapes: from typical to large deviations
Valentina Ros
In these notes we discuss tools and concepts that emerge when studying high-dimensional random landscapes, i.e., random functions on high-dimensional spaces. As an illustrative exa…
Triplets of local minima in a high-dimensional random landscape: Correlations, clustering, and memoryless activated jumps
Alessandro Pacco, Alberto Rosso, Valentina Ros
We compute the distribution of triplets of stationary points in the energy landscape of the spherical p-spin model, by evaluating the quenched three-point complexity by means of th…
Curvature-driven pathways interpolating between stationary points: the case of the pure spherical 3-spin model
Alessandro Pacco, Giulio Biroli, Valentina Ros
This paper focuses on characterizing the energy profile along pathways connecting different regions of configuration space in the context of a prototypical glass model, the pure sp…
Dynamical Instantons and Activated Processes in Mean-Field Glass Models
V. Ros, G. Biroli, C. Cammarota
We focus on the energy landscape of a simple mean-field model of glasses and analyze activated barrier-crossing by combining the Kac-Rice method for high-dimensional Gaussian lands…
Complexity of energy barriers in mean-field glassy systems
Valentina Ros, Giulio Biroli, Chiara Cammarota
We analyze the energy barriers that allow escapes from a given local minimum in a mean-field model of glasses. We perform this study by using the Kac-Rice method and computing the…
Localized systems coupled to small baths: from A to Z
D. A. Huse, R. Nandkishore, F. Pietracaprina +2
We investigate what happens if an Anderson localized system is coupled to a small bath, with a discrete spectrum, when the coupling between system and bath is specially chosen so a…
