Out-of-equilibrium response and fluctuation-dissipation violations across scales in flocking systems

Flocking systems are known to be strongly out of equilibrium. Energy input occurs at the individual level to ensure self-propulsion, and the individual motility, in turn, contributes to ordering, enhancing information propagation and strengthening collective motion. However, even beyond ordering, a...
