title: Effect of reorientation statistics on torque response of self-propelled particles.
abstract: We consider the dynamics of self-propelled particles subject to external torques. Two models for the reorientation of self-propulsion are considered: run-and-tumble particles and active Brownian particles. Using the standard tools of nonequilibrium statistical mechanics we show that the run and tumble particles have a more robust response to torques. This macroscopic signature of the underlying reorientation statistics can be used to differentiate between the two types of self-propelled particles.
