  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The defining
    feature of active particles is that they constantly propel themselves by locally
    converting chemical energy into directed motion. 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>"
