Thermodynamics of chiral particles

We developed a thermodynamic framework for chiral active matter, establishing an equation of state that connects the microscopic properties of rotating active particles to macroscopic quantities such as pressure and temperature. Our findings provide new insights into the collective behaviour of chiral active systems, paving the way for the design and control of autonomous active machines and microfluidic devices.

Chiral mini-robots (black disks) follow circular trajectories (grey curved paths), exerting pressure on the system boundaries. This generates an increase in the effective temperature and induces edge currents (blue arrows).
