Nonreciprocal interactions between particles — Caption

Nonreciprocal interactions occur when one particle influences another more strongly than it is influenced in return, breaking action–reaction symmetry. This figure illustrates how unequal electrohydrodynamic attraction between differently sized particles generates nonreciprocal interactions and self-propelled particle pairs.
