We study long range density fluctuations (hyperuniformity) in two-dimensional jammed packings of bidisperse droplets. Taking advantage of microfluidics, we systematically span a large range of size and concentration ratios of the two droplet populations. We identify various defects increasing long range density fluctuations mainly due to organization of local particle environment. By choosing an appropriate bidispersity, we fabricate materials with a high level of hyperuniformity. Interesting transparency properties of these optimized materials are established based on numerical simulations.

优化自组装双分散乳液的超均匀性

我们研究了双分散液滴的二维阻塞堆积中的远距离密度波动（不均匀性）。利用微流控技术，我们系统地跨越了两个液滴总体的大小和浓度比的大范围。我们发现主要由于局部粒子环境的组织而导致增加远距离密度波动的各种缺陷。通过选择合适的双分散度，我们可以制造出高度均匀的材料。这些优化材料的有趣的透明性是基于数值模拟建立的。
