Abstract:

The answer to the question, ’How far from equilibrium is active matter?’ is not unique. It depends on the reference equilibrium state which, in turn, depends on the time-reversal signature assigned to the dynamical variables in question. In addressing this question we show precisely what observed behaviours, as defined by a suitable notion of entropy production, distinguish an active system from a passive counterpart with the same spatial symmetries.
