Equilibrium Instability from Cooperative Interactions in a System of
Brownian Agents

Abstract
We show, by building a minimal Vicsek's inspired model, that cooperative interactions among Brownian agents,
as those used in modeling ocking behavior, leads to instability of the thermodynamic branch characterized
by a vanishing average direction of motion (disordered phase) of the system. At a critical value of the coupling,
the system develops a global nonvanishing particle current (cooperative behavior) taking the system far from
the equilibrium branch.
