Opinion dynamics with emergent collective memory: the impact of a long and heterogeneous news history
Gioia Boschi, Chiara Cammarota, Reimer Kühn
In modern society people are being exposed to numerous information, with some of them being frequently repeated or more disruptive than others. In this paper we use a model of opin…
Properties of equilibria and glassy phases of the random Lotka-Volterra model with demographic noise
Ada Altieri, Felix Roy, Chiara Cammarota +1
In this letter we study a reference model in theoretical ecology, the disordered Lotka-Volterra model for ecological communities, in the presence of finite demographic noise. Our t…
Dynamical systems on large networks with predator-prey interactions are stable and exhibit oscillations
Andrea Marcello Mambuca, Chiara Cammarota, Izaak Neri
We analyse the stability of linear dynamical systems defined on sparse, random graphs with predator-prey, competitive, and mutualistic interactions. These systems are aimed at mode…
Complex Dynamics in Simple Neural Networks: Understanding Gradient Flow in Phase Retrieval
Stefano Sarao Mannelli, Giulio Biroli, Chiara Cammarota +3
Despite the widespread use of gradient-based algorithms for optimizing high-dimensional non-convex functions, understanding their ability of finding good minima instead of being tr…
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…
Dynamical Mean-Field Theory and Aging Dynamics
Ada Altieri, Giulio Biroli, Chiara Cammarota
Dynamical Mean-Field Theory (DMFT) replaces the many-body dynamical problem with one for a single degree of freedom in a thermal bath whose features are determined self-consistentl…
