We study microscopic engines that use a single active particle as their "working medium." Part of the energy required to drive the directed motion of the particle can be recovered as work, even at a constant temperature. A wide class of synthetic active particles can be captured by schematically accounting for the chemical degrees of freedom that power the directed motion without having to resolve the exact microscopic mechanism. We derive analytical results for the quasistatic thermodynamic…

Diffusion coefficient and power spectrum of active particles with a microscopically reversible mechanism of self-propelling.

Catalytically active macromolecules are envisioned as key building blocks in the development of artificial nanomotors. However, theory and experiments report conflicting findings regarding their

Optimal power extraction from active particles with hidden states

It is argued that the theoretical bounds derived in this work are those against which the performance of realistic active matter engines should be compared.



Active engines: Thermodynamics moves forward

The study of thermal heat engines was pivotal to establishing the principles of equilibrium thermodynamics, with implications far wider than only engine optimization. For nonequilibrium systems,

Autonomous Engines Driven by Active Matter: Energetics and Design Principles

Surprisingly, this approach reveals that the interaction with the passive obstacle can mediate cooperativity between otherwise noninteracting active particles, which enhances the extracted power per active particle significantly.

Colloidal heat engines: a review.

The theoretical framework of stochastic thermodynamics is revisited, and some guidance on how the work extracted from colloidal heat engines can be used to generate net particle or energy currents is provided, proposing a new generation of experiments with colloidal systems.

Thermodynamics of Active Field Theories: Energetic Cost of Coupling to Reservoirs

The hallmark of active matter is the autonomous directed motion of its microscopic constituents driven by consumption of energy resources. This leads to the emergence of large scale dynamics and

Stochastic heat engine using an active particle.

It is shown that the presence of activity leads to an enhanced performance of the engine, and the efficiency can be improved by increasing the activity strength for all cycle time, including the nonquasistatic regime.

Realization of a micrometre-sized stochastic heat engine

An optically trapped colloidal particle serves as the first realization of a stochastic thermal engine, extending our understanding of the thermodynamics behind the Carnot cycle to microscopic scales

Hidden entropy production and work fluctuations in an ideal active gas.

This work quantifies the irreversibility for a noninteracting active particle in two dimensions by treating both conjugated and time-reversed dynamics and identifies a hidden rate of entropy production required to maintain persistence and prevent the rapidly relaxing momenta from thermalizing, even in the limit of very large friction.

A micrometre-sized heat engine operating between bacterial reservoirs

A colloidal particle connected to suspensions of motile bacteria forms a model system for studying microscale engines in contact with active baths. The engine outperforms its passive counterparts due

This work considers the situation when the difference of chemical potential between the two species (the driving affinity) can be assumed to be constant, and derives the thermodynamically consistent equations of motion.

Energy transduction of isothermal ratchets: generic aspects and specific examples close to and far from equilibrium.

We study the energetics of isothermal ratchets which are driven by a chemical reaction between two states, and operate in contact with a single heat bath of constant temperature. We discuss generic
