Optimized Large Hyperuniform Binary Dipolar Colloidal Suspensions in Two Dimensions

We have developed a protocol to guide experimentalists to fabricate large disordered hyperuniform two-phase system in two dimensions by binary colloidal particles. In our model, colloidal particles are doped such that it induces dipole-dipole interactions when a magnetic field is applied. We show that despite each component is not hyperuniform, there exists an optimal composition that makes the resulting two-phase system effectively hyperuniform. By changing magnetic fields or the doping level/size of particles, the system can self-organize into tunable structures. Our approach provides a general solution for making large hyperuniform materials in labs in an efficient manner.
