在过去的两年中，我们看到了令人兴奋的实验发现，以非平凡的准式远程顺序 - 一种新的物质形式，称为“柔软的”两组树枝状大分子晶体的系统；对准晶体和软物质的基本研究，同时还要基于具有独特的物理特性的自组装纳米材料的新应用，以利用ic骨菌度，例如完整和同性恋光子带隙材料。对软准晶体的新兴领域的简明综述，表明存在两个自然长度尺度以及三体相互作用，可能构成其稳定性的根本来源。
In the last two years we have witnessed the exciting experimental discovery of soft matter with nontrivial quasiperiodic long-range order–a new form of matter termed a soft quasicrystal. Two groups have independently discovered such order in soft matter: Zeng et al. in a system of dendrimer liquid crystals; and Takano et al. in a system of ABC star-shaped polymers. These newly discovered soft quasicrystals not only provide exciting platforms for the fundamental study of both quasicrystals and of soft matter, but also hold the promise for new applications based on self-assembled nanomaterials with unique physical properties that take advantage of the quasiperiodicity, such as complete and isotropic photonic band-gap materials. Here we provide a concise review of the emerging field of soft quasicrystals, suggesting that the existence of two natural length-scales, along with three-body interactions, may constitute the underlying source of their stability.
