摘要:

基于三维伊辛模型中自旋团簇的热涨落及其二维截面,给出了三维伊辛模型的随机界面表示.已经进行了大量的模拟,以测量作为温度的函数的不同晶格尺寸的全球界面宽度,这被示出为信号的临界性的模型在$T_c$通过形成一个大小无关的尖点在3D中,随着一个紧急的超粗糙化在其2D截面。我们发现超粗糙态伴随着一个内在的反常标度行为的局部性质,其特征在于一组几何指数,这是相同的那些为纯二维伊辛模型。

英文摘要:

We present a random-interface representation of the three-dimensional (3D) Ising model based on thermal fluctuations of a uniquely defined geometric spin cluster in the 3D model and its 2D cross section. Extensive simulations have been carried out to measure the global interfacial width as a function of temperature for different lattice sizes which is shown to signal the criticality of the model at $T_c$ by forming a size-independent cusp in 3D, along with an emergent super-roughening at its 2D cross section. We find that the super-rough state is accompanied by an intrinsic anomalous scaling behavior in the local properties characterized by a set of geometric exponents which are the same as those for a pure 2D Ising model.
