论文摘要
我们提出了一种田间理论，以描述表面自发地与其批量环境自发交换物质的组成。通过仅假设系统中的物质保护，我们显示了广泛的数值模拟，这些模拟取决于物质汇率，表面出现了复杂的图案成分分布。对于一维系统，我们在分析和数字上显示，牢固的变形被逮捕，因此域具有特征性的长度尺度。我们的结果表明，细胞膜中异质脂质组成的原因可能是简单的物理术语合理的。
We present a field theory to describe the composition of a surface spontaneously exchanging matter with its bulk environment. By only assuming matter conservation in the system, we show with extensive numerical simulations that, depending on the matter exchange rates, a complex patterned composition distribution emerges in the surface. For one-dimensional systems we show analytically and numerically that coarsening is arrested and as a consequence domains have a characteristic length scale. Our results show that the causes of heterogeneous lipid composition in cellular membranes may be justified in simple physical terms.
