摘要翻译:
采用正则蒙特卡罗模拟技术,对Nambu和Goto的表面模型进行了统计力学研究。该模型由哈密顿量中的面积能项和一维弯曲能项定义。我们发现该模型具有大量的相位变化;球形相、平面相、长线性相、短线性相、蠕虫状相和塌陷相。几乎所有相邻的两个相都被不连续的跃迁分开。在球面相和平面相的表面上都看不到表面涨落,这也是值得注意的。

英文摘要:
A surface model of Nambu and Goto is studied statistical mechanically by using the canonical Monte Carlo simulation technique on a spherical meshwork. The model is defined by the area energy term and a one-dimensional bending energy term in the Hamiltonian. We find that the model has a large variety of phases; the spherical phase, the planar phase, the long linear phase, the short linear phase, the wormlike phase, and the collapsed phase. Almost all two neighboring phases are separated by discontinuous transitions. It is also remarkable that no surface fluctuation can be seen in the surfaces both in the spherical phase and in the planar phase.
