This active self-propulsion prevents them from equilibrating with their thermal environment (e.g. an aqueous solution), thus keeping them permanently out of equilibrium. Nevertheless, the spatial dynamics of active particles might share certain equilibrium features, in particular in the steady state. We here focus on the time-reversal symmetry of individual spatial trajectories as a distinct equilibrium characteristic. We investigate to what extent the steady-state trajectories of a trapped active particle obey or break this time-reversal symmetry. Within the framework of active Ornstein–Uhlenbeck particles we find that the steady-state trajectories in a harmonic potential fulfill path-wise time-reversal symmetry exactly, while this symmetry is typically broken in anharmonic potentials.</jats:p>","lang":"eng"}],"publication_identifier":{"issn":["1742-5468"]},"type":"journal_article","year":"2021","issue":"3","doi":"10.1088/1742-5468/abe6fd","intvolume":"      2021","_id":"32243","keyword":["Statistics","Probability and Uncertainty","Statistics and Probability","Statistical and Nonlinear Physics"],"volume":2021,"author":[{"first_name":"Lennart","last_name":"Dabelow","full_name":"Dabelow, Lennart"},{"first_name":"Stefano","last_name":"Bo","full_name":"Bo, Stefano"},{"full_name":"Eichhorn, Ralf","last_name":"Eichhorn","first_name":"Ralf"}],"citation":{"ama":"Dabelow L, Bo S, Eichhorn R.
