二维界面的普适性态和Nambu-Goto弦的降维

Universal behaviour of interfaces in 2d and dimensional reduction of Nambu-Goto strings

M. Billo, M. Caselle, L. Ferro

摘要:

我们提出了一个简单有效的模型,用于描述接口的二维统计模型,基于一阶处理的行动对应的接口的长度。该模型对界面自由能的普遍预测与二维伊辛模型的精确计算结果一致。该模型表现为三维界面的Nambu-Goto字符串描述的降维,即,毛细波模型的一部分。

英文摘要:

We propose a simple effective model for the description of interfaces in 2d statistical models, based on the first-order treatment of an action corresponding to the length of the interface. The universal prediction of this model for the interface free energy agrees with the result of an exact calculation in the case of the 2d Ising model. This model appears as a dimensional reduction of the Nambu-Goto stringy description of interfaces in 3d, i.e., of the capillary wave model.
