Calorimetry for active systems

We provide the theoretical basis of calorimetry for a class active particles subject to thermal noise. Simulating AC-calorimetry, we numerically evaluate heat capacity run-and-tumble in double-well and periodic potentials, systems with flashing potential. Low-temperature Schottky-like peaks show role activity indicate shape transitions, while regimes negative appear at higher propulsion speeds. From there, significant increase capacities may be inferred low temperatures, as well possibility diagnostic tools self-motile artificial or biomimetic based on measurements.
