By changing the active noise correlation length and time, we can tune the sizes and lifetimes of the clusters.

We tested our method on a system of volume-excluding colloidal particles. At thermal equilibrium, this system is fairly “boring,” exhibiting little structure. In contrast, active noise causes these particles to form striking dynamic structures, such as rotating clusters.

How do we harness directed motion to assemble life-like materials? We developed a computational method to help answer this question. While active fluid flows look chaotic, they have a well-defined correlation length and time. We thus modeled active fluids via correlated noise.
