摘要翻译：
利用我们最近提出的一种分析具有θ项的系统的θ依赖关系的方法，研究了Cp^1在θ=pi时的临界行为。我们在强耦合区之外找到了一个区域，验证了霍尔丹猜想。然而，在拓扑耦合k=1时，临界线不属于Wess-Zumino-Novikov-Witten模型的普适类，因为它表现出连续变化的临界指数。

英文摘要：
  Using an approach to analyze the theta dependence of systems with a theta-term we recently proposed, the critical behavior of CP^1 at theta=pi is studied. We find a region outside the strong coupling regime where Haldane's conjecture is verified. The critical line however does not belong to the universality class of the Wess-Zumino-Novikov-Witten model at topological coupling k=1 since it shows continuously varying critical exponents.
