Many kinds of active particles, such as bacteria or active colloids, move ina thermostatted fluid by means of self-propulsion. Energy injected by such anon-equilibrium force is eventually dissipated as heat in the thermostat. Sincethermal fluctuations are much faster and weaker than self-propulsion forces,they are often neglected, blurring the identification of dissipated heat intheoretical models. For the same reason, some freedom - or arbitrariness -appears when defining entropy production. Recently three different recipes todefine heat and entropy production have been proposed for the same model wherethe role of self-propulsion is played by a Gaussian coloured noise. Here wecompare and discuss the relation between such proposals and their physicalmeaning. One of these proposals takes into account the heat exchanged with anon-equilibrium active bath: such an "active heat" satisfies the originalClausius relation and can be experimentally verified.

Clausius relation for active particles: what can we learn from fluctuations?
