Modeling the efficiency and effective temperature of bacterial heat engines
Original language description
We present a Brownian dynamics simulation of the bacterial Stirling engine studied by Krishnamurthy et al. [Nat. Phys. 12, 1134 (2016)]. In their experimental setup, an overdamped colloid in an optical trap with time-modulated stiffness interacts with a bacterial bath that we represent by an ensemble of overdamped active particles. In the parameter regime of the experiment the thermodynamic performance is governed by an effective temperature and can be parametrized analytically by active Brownian particle models. We quantitatively reproduce the efficiencies reported for the experiments under the assumption that energy exchange with the bath during isochores of the cycle is entirely recuperated and in agreement with the second law.
