To calculate $\\Pi$, the link between the entropy production and dissipation of heat rate is explored. By analyzing the Kramers equation in a stationary state, alternative formulations of $\\Pi$ are obtained and the virial theorem for active particles is derived. Exact results are obtained for particles in an unconfined environment and in a harmonic trap. In both cases, $\\Pi$ is independent of temperature. In contrast, for active particles in 1D box, thermal fluctuations are found to reduce $\\Pi$.", "revisions": [ { "version": "v1", "updated": "2022-11-03T18:26:34.000Z" } ], "analyses": { "keywords": [ "active particles", "underdamped regime", "entropy production rate", "thermal fluctuations", "heat rate" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
