Universal Dynamics of a Passive Particle Driven by Brownian Motion
Universal Dynamics of a Passive Particle Driven by Brownian Motion
We investigate the overdamped dynamics of a `passive' particle driven by nonreciprocal interaction with a `driver' Brownian particle. When the interaction between them is short-ranged, the long-time behavior of the driven particle is remarkably universal -- the mean-squared displacement (MSD) and the typical position of the driven particle exhibits the …
