Self-organization in heterogeneous and non-reciprocal regime
Coupled physical interactions induce emergent collective behaviors of many interacting objects. Biological systems are typically heterogeneous and interact via non-reciprocal interactions for various purposes, such as locomotion and self-organization. Investigating the role of heterogeneity and nonreciprocity in the behavior of nonequilibrium systems would allow us to expand our understanding of various complex biological systems. Research on self-organization in microscopic systems typically includes study of systems consisting identical agents that interact via reciprocal interactions. We studied the effect of size heterogeneity in microrobot collectives composed of circular, magnetic microdisks on a fluid–air interface [1]. We demonstrated that heterogenous collectives separate by size and the extent of separation can be programmed using a uniform magnetic field. We also studied self-organization in a system of identical and heterogeneous magnetic microdisks that breaks action-reaction reciprocity via fluid-mediated hydrodynamic interactions, on demand [2]. Our work furthers insights into self-organization in the non-reciprocal regime and in heterogeneous microrobot collectives and moves us closer to the goal of applying such collectives to programmable self-assembly and active matter.
