abstract
One of the most fundamental quests in the physics of active matter concerns the existence of a comprehensive theory for its macroscopic properties, i.e. an ``active thermodynamics''. Here, we derive and experimentally verify key elements of the active thermodynamics of ideal chiral active gases, unveiling edge currents and odd diffusivity as their peculiar features. Our main results are the derivation of an equation of state relating density and pressure via a chirality-dependent effective temperature, the derivation of Fick's law including the full diffusion matrix predicting odd diffusion, and the exact prediction of edge currents at container walls that nonmonotonically depend on chirality.

Boundary curvature induces wall accumulation in non-motile chiral active particles confined in circular geometries via tangential wall forces, as shown by simulations and hydrodynamics.
A chirality-switching model of 2D active particles produces robust topological edge currents in confinement and at phase-separation interfaces, distinct from standard motility-induced phase separation.
Odd mobility in a two-temperature Brownian dimer produces handed correlations between particles and increases thermal conductance without altering net heat flow or dissipation under handedness reversal.
Chiral active fluids form rotating bubbles that dynamically break up and reform in a sparkling instability at optimal packing fractions, as predicted by coarse-grained hydrodynamics.
Edge fluxes in chiral fluids equal the average odd stress in confined geometries or the jump in odd stress across interfaces in phase-separated systems.
Augmented bristlebots with self-aligning torque and chiral drift exhibit geometry-controlled edge currents and rectified transport via a nautilus-shaped ratchet.
