Dynamical maximum entropy approach to flocking
Andrea Cavagna, Irene Giardina, Francesco Ginelli +4
We derive a new method to infer from data the out-of-equilibrium alignment dynamics of collectively moving animal groups, by considering the maximum entropy distribution consistent…
Collective behaviour without collective order in wild swarms of midges
A. Attanasi, A. Cavagna, L. Del Castello +8
Collective behaviour is a widespread phenomenon in biology, cutting through a huge span of scales, from cell colonies up to bird flocks and fish schools. The most prominent trait o…
Localization protected quantum order
David A. Huse, Rahul Nandkishore, Vadim Oganesyan +2
Closed quantum systems with quenched randomness exhibit many-body localized regimes wherein they do not equilibrate even though prepared with macroscopic amounts of energy above th…
Superfluid transport of information in turning flocks of starlings
Alessandro Attanasi, Andrea Cavagna, Lorenzo Del Castello +8
Collective decision-making in biological systems requires all individuals in the group to go through a behavioural change of state. During this transition, the efficiency of inform…
