Non-equilibrium phase transition in the Brownian Ising Model: field theory, renormalization group, and exact results
Mattia Scandolo, Luca Di Carlo
We present a complete field-theoretical renormalization-group (RG) analysis of the Brownian Ising Model (BIM), in which a order parameter is coupled to a passive con…
Non-equilibrium coupling to a diffusing density breaks Ising universality
Mattia Scandolo, Johannes Pausch, Michael E. Cates +1
The Ising universality class is remarkably robust to non-equilibrium perturbations, which generically flow to zero under renormalization. We show that this robustness fails when an…
Information bounds the robustness of self-organized systems
Nicolas Romeo, David G. Martin, Mattia Scandolo +3
Self-organized systems, from synthetic nanostructures to developing organisms, are composed of fluctuating units capable of forming robust functional structures despite noise. Here…
Spin-Waves without Spin-Waves: A Case for Soliton Propagation in Starling Flocks
Andrea Cavagna, Guido Cimino, Javier Cristín +10
Collective turns in starling flocks propagate linearly with negligible attenuation, indicating the existence of an underdamped sector in the dispersion relation. Beside granting li…
Active Ising Models of Flocking: A Field-Theoretic Approach
Mattia Scandolo, Johannes Pausch, Michael E. Cates
Using an approach based on Doi-Peliti field theory, we study several different Active Ising Models (AIMs), in each of which collective motion (flocking) of self-propelled particles…
Evidence of fluctuation-induced first-order phase transition in active matter
Luca Di Carlo, Mattia Scandolo
We study the properties of the Malthusian Toner-Tu theory in its near ordering phase. Because of the birth/death process, characteristic of this Malthusian model, density fluctuati…
Natural Swarms in Dimensions
Andrea Cavagna, Luca Di Carlo, Irene Giardina +5
The dynamical critical exponent of natural swarms of insects is calculated using the renormalization group to order . A novel fixed point emerges, where both activity a…
Dynamical renormalization group for mode-coupling field theories with solenoidal constraint
Andrea Cavagna, Luca di Carlo, Irene Giardina +3
The recent inflow of empirical data about the collective behaviour of strongly correlated biological systems has brought field theory and the renormalization group into the biophys…
