标题： Scaling behavior of the four-point renormalized coupling constant in the two dimensional O(2) and O(3) non-linear sigma models

摘要： 我们报告了通过蒙特卡罗模拟在二维 O(2) 和 O(3) 非线性 sigma 模型的格点版本的连续极限下计算的四点重整化耦合常数的热力学值。 在每种情况下，耦合常数的临界指数为零，这导致了超尺度（非平凡性）。 显示英文摘要

摘要： We report thermodynamic values of four-point renormalized coupling constant calculated by Monte Carlo simulations in the continuum limits of the lattice versions of the two-dimensional O(2) and O(3) non-linear sigma models. In each case the critical index of the coupling constant vanishes, which leads to hyperscaling (non-triviality).
