Density-protected states in active matter under virtual confinement
Giuseppe Fava, Francesco Ginelli, Benoît Mahault
We investigate photo-responsive structure formation in a minimal model of dry active nematics. Combining microscopic simulations with the analysis of the corresponding hydrodynamic…
Learning to flock in open space by avoiding collisions and staying together
Martino Brambati, Antonio Celani, Marco Gherardi +1
We investigate the emergence of cohesive flocking in open, boundless space using a multi-agent reinforcement learning framework. Agents integrate positional and orientational infor…
Boundary symmetry breaking of flocking systems
Leonardo Lenzini, Giuseppe Fava, Francesco Ginelli
We consider a flocking system confined transversally between two infinite reflecting parallel walls separated by a distance . Infinite or periodic boundary conditions are…
Strong Casimir-like Forces in Flocking Active Matter
Giuseppe Fava, Andrea Gambassi, Francesco Ginelli
Confining in space the equilibrium fluctuations of statistical systems with long-range correlations is known to result into effective forces on the boundaries. Here we demonstrate…
A statistical mechanics framework for Bayesian deep neural networks beyond the infinite-width limit
R. Pacelli, S. Ariosto, M. Pastore +3
Despite the practical success of deep neural networks, a comprehensive theoretical framework that can predict practically relevant scores, such as the test accuracy, from knowledge…
Signatures of directed and spontaneous flocking
Martino Brambati, Giuseppe Fava, Francesco Ginelli
Collective motion - or flocking - is an emergent phenomena that underlies many biological processes of relevance, from cellular migrations to animal groups movement. In this work,…
