Abstract
We study the statistics, in stationary conditions, of the work Wτ done by the active force in different systems of self-propelled particles in a time τ. We show the existence of a critical value Wτ† such that fluctuations with Wτ>Wτ† correspond to configurations where interaction between particles plays a minor role whereas those with WτFile in questo prodotto:
