反铁磁Potts模型中两个拓扑相的重叠

Overlap of two topological phases in the antiferromagnetic Potts model

Ran Zhao, Chengxiang Ding, Youjin Deng

摘要:

通过控制涡核能量,三态铁磁Potts模型可以表现出两种类型的拓扑范式,包括准长程有序相和涡旋晶格相[PRL 116,097206(2016)]。在这里,通过使用一种有效的蠕虫算法的蒙特卡罗模拟,我们证明了通过控制涡核能量,反铁磁Potts模型也可以表现出两个拓扑相,更有趣的是,两个拓扑相可以相互重叠。

英文摘要:

By controlling the vortex core energy, the three-state ferromagnetic Potts model can exhibit two types of topological paradigms, including the quasi-long-range ordered phase and the vortex lattice phase [PRL 116, 097206 (2016)]. Here, by Monte Carlo simulations using an effective worm algorithm, we show that by controlling the vortex core energy, the antiferromagnetic Potts model can also exhibit the two topological phases, more interestingly, the two topological phases can overlap with each other.
