There is a variety of situations in which Newton’s third law is violated. Generally, the action-reaction symmetry can be broken for mesoscopic particles, when their effective interactions are mediated by a nonequilibrium environment. Here, we investigate different classes of nonreciprocal interactions relevant to real experimental situations and present their basic statistical mechanics analysis. We show that in mixtures of particles with such interactions, distinct species acquire distinct kinetic temperat
When a planar bilayer of colloids is exposed to perpendicular flow, the wakes generated downstream from each particle mediate their effective interactions. Most notably, the particle-wake interactions break the action-reaction symmetry for the colloids in different layers. Under quite general conditions we show that, if the interaction nonreciprocity exceeds a certain threshold, this creates an active dispersion of self-propelled particle clusters. The emerging activity promotes unusual melting scenarios an
