A basic statistical mechanics analysis of many-body systems with non-reciprocal pair interactions is presented. Different non-reciprocity classes in two- and three-dimensional binary (relevant to real experimental situations) are investigated, where the action-reaction symmetry broken for interaction between different species. The asymmetry characterized by a parameter $\Delta$, which ratio reciprocal forces. It shown that "constant" (when $\Delta$ independent interparticle distance $r$) one...
In a bilayered system of particles with wake-mediated interactions, the action-reaction symmetry for effective forces between different layers is broken. Under quite general conditions we show that, if interaction nonreciprocity exceeds certain threshold, this creates an active dispersion self-propelled clusters Brownian particles. The emerging activity promotes unusual melting scenarios and enormous diffusivity in dense fluid. Our results are obtained by computer simulation analytical...
Nonreciprocal effective interaction forces can occur between mesoscopic particles in colloidal suspensions that are driven out of equilibrium. These violate Newton's third law actio = reactio on coarse-grained length and time scales. Here we explore the statistical mechanics Brownian with nonreciprocal interactions. Our model system is a binary fluid mixture spherically symmetric, diffusiophoretic particles, focus time-averaged particle pair- triplet-correlation functions. Based many-body...
