  Biological and synthetic microswimmers display a wide range of swimming
trajectories depending on driving forces and torques. In this paper we consider
a simple overdamped model of self-propelled particles with a constant
self-propulsion speed, but an angular velocity that varies in time.
Specifically, we consider the case of both deterministic and stochastic angular
velocity reversal, mimicking several synthetic active matter systems like
propelled droplets. The orientational correlation function and effective
diffusivity is studied using Langevin dynamics simulations and perturbative
methods.
