Renormalization group study of marginal ferromagnetism
Andrea Cavagna, Antonio Culla, Tomás S. Grigera
When studying the collective motion of biological groups a useful theoretical framework is that of ferromagnetic systems, in which the alignment interactions are a surrogate of the…
Marginal speed confinement resolves the conflict between correlation and control in natural flocks of birds
Andrea Cavagna, Antonio Culla, Xiao Feng +7
Speed fluctuations of individual birds in natural flocks are moderate, due to the aerodynamic and biomechanical constraints of flight. Yet the spatial correlations of such fluctuat…
Low-temperature marginal ferromagnetism explains anomalous scale-free correlations in natural flocks
Andrea Cavagna, Antonio Culla, Luca Di Carlo +2
We introduce a new ferromagnetic model capable of reproducing one of the most intriguing properties of collective behaviour in starling flocks, namely the fact that strong collecti…
