分区表面模型的相变

Phase transition of compartmentalized surface models

Hiroshi Koibuchi

摘要:

用蒙特卡罗模拟研究了两种不同的表面模型在三角形区域上的运动。发现两个模型都经历了一级坍缩和一级表面涨落的转变。第一个模型是流体表面模型。顶点只能在区域内部自由扩散,由于区域边界,它们被禁止在表面上自由扩散。第二个是骨架模型。骨架模型的表面形状仅由域边界保持,域边界是具有刚性连接的线性链。因此,我们可以得出结论,一级转变的发生与表面形状是由骨架(=畴边界)还是由表面本身机械地保持无关。

英文摘要:

Two types of surface models have been investigated by Monte Carlo simulations on triangulated spheres with compartmentalized domains. Both models are found to undergo a first-order collapsing transition and a first-order surface fluctuation transition. The first model is a fluid surface one. The vertices can freely diffuse only inside the compartments, and they are prohibited from the free diffusion over the surface due to the domain boundaries. The second is a skeleton model. The surface shape of the skeleton model is maintained only by the domain boundaries, which are linear chains with rigid junctions. Therefore, we can conclude that the first-order transitions occur independent of whether the shape of surface is mechanically maintained by the skeleton (= the domain boundary) or by the surface itself.
