We show that rotating membrane inclusions can crystallize due to combined hydrodynamic and steric interactions. Alone, steric repulsion of unconfined particles, even with thermal fluctuations, does not lead to crystallization, nor do rotational hydrodynamic interactions which allow only a marginally stable lattice. Hydrodynamic interactions enable particles to explore states inaccessible to a non-rotational system, yet, unlike Brownian motion, Hamiltonian conservation confines the ensemble which, when combined with steric interactions, anneals into a stable crystal state.

旋转膜蛋白快速结晶

我们显示旋转的膜夹杂物可以结晶由于组合的水动力和空间相互作用。即使存在热波动，未约束颗粒的单独空间排斥也不会导致结晶，旋转流体动力相互作用也不会导致仅略微稳定的晶格。流体动力相互作用使粒子能够探索非旋转系统难以接近的状态，但是，与布朗运动不同，哈密顿量守恒将集合体限制在与空间相互作用结合时退火成稳定的晶体状态。
