我们研究了在柔性流体膜中引起局部各向异性曲率的夹杂物的集体行为。明确计算了一般各向异性夹杂物的 N 体相互作用能，包括多体相互作用。发现内含物之间的长程吸引相互作用足够强以引起聚集。蒙特卡罗模拟显示了从紧凑簇到在线或圆上聚集的转变。这些结果可能与生物膜中的蛋白质或与表面活性剂膜结合的胶体颗粒有关。
We study the collective behavior of inclusions inducing local anisotropic curvatures in a flexible fluid membrane. The N-body interaction energy fbr general anisotropic inclusions is calculated explicitly, including multi-body interactions. Long-range attractive interactions between inclusions are found to be sufficiently strong to induce aggregation. Monte Carlo simulations show a transition from compact clusters to aggregation on lines or circles. These results might be relevant to proteins in biological membranes or colloidal particles bound to surfactant membranes.
