我们构建了一个拓扑有序的晶格模型（Kagome量子自旋液体），并用无偏量子蒙特卡罗模拟求解。本文揭示了一个三阶段任意子凝聚，它具有从$\mathbb Z_2\boxtimes\mathbb Z_2$拓扑序到$\mathbb Z_2$拓扑序，最后到平凡对称相的两个跃迁.这些结果提供了量子磁体中拓扑序之间相变的具体例子。所设计的量子自旋液体模型及其数值解为进一步研究残余任意子凝聚提供了一个平台。
We construct a lattice model of topological order (Kagome quantum spin liquids) and solve it with unbiased quantum Monte Carlo simulations. A three-stage anyon condensation with two transitions from a $\mathbb Z_2\boxtimes\mathbb Z_2$ topological order to a $\mathbb Z_2$ topological order and eventually to a trivial symmetric phase has been revealed. These results provide concrete examples of phase transitions between topological orders in quantum magnets. The designed quantum spin liquid model and its numerical solution offer a playground for further investigations on vestigial anyon condensation.
