受限几何条件下囊泡液滴的简单模型
A simple model of a vesicle drop in a confined geometry
摘要：
我们提出了一个二维定向行走模型的精确解的下降，或半囊泡，限制在两个墙壁之间，并连接到一个墙壁。该模型也是最近研究的空间稳定的聚合物模型的概括。我们探讨的竞争之间的粘性潜力的两个墙壁和系统中的一个压力一样的长期的效果。我们表明，负压确保了液滴/聚合物不受限制时，墙壁是一个宏观的距离分开。
英文摘要：
We present the exact solution of a two-dimensional directed walk model of a drop, or half vesicle, confined between two walls, and attached to one wall. This model is also a generalisation of a polymer model of steric stabilisation recently investigated. We explore the competition between a sticky potential on the two walls and the effect of a pressure-like term in the system. We show that a negative pressure ensures the drop/polymer is unaffected by confinement when the walls are a macroscopic distance apart.
