Local equilibrium in bird flocks [PDF]
Nature Physics, 2015 The correlated motion of flocks is an example of global order emerging from local interactions. An essential difference with respect to analogous ferromagnetic systems is that flocks are active: animals move relative to each other, dynamically ...

The confusion effect when attacking simulated three-dimensional starling flocks
Royal Society Open Science, 2017 The confusion effect describes the phenomenon of decreasing predator attack success with increasing prey group size. However, there is a paucity of research into the influence of this effect in coherent groups, such as flocks of European starlings ...

Nonsymmetric Interactions Trigger Collective Swings in Globally Ordered Systems [PDF]
, 2017 Many systems in nature, from ferromagnets to flocks of birds, exhibit ordering phenomena on the large scale. In condensed matter systems, order is statistically robust for large enough dimensions, with relative fluctuations due to noise vanishing with ...
