论文摘要
在本文中，我们研究了五态POTTS抗铁磁体的相图。这个问题很重要，因为Delfino和Tartaglia最近表明，允许五态POTTS抗fiferromagnet中的二阶过渡，并且在数值基础上出现了分配后的甲状腺晶格作为候选这种过渡的候选者。通过使用高精度蒙特卡洛模拟和两种互补分析方法，我们得出结论，存在有限的一阶过渡点。这个分离了顺磁性高温相，而五个相共存的低温相。这种相变非常弱，因为它的潜热（每个边缘）比其他众所周知的弱弱一阶相变小两个数量级。
In this paper we study the phase diagram of the five-state Potts antiferromagnet on the bisected-hexagonal lattice. This question is important since Delfino and Tartaglia recently showed that a second-order transition in a five-state Potts antiferromagnet is allowed, and the bisected-hexagonal lattice had emerged as a candidate for such a transition on numerical grounds. By using high-precision Monte Carlo simulations and two complementary analysis methods, we conclude that there is a finite-temperature first-order transition point. This one separates a paramagnetic high-temperature phase, and a low-temperature phase where five phases coexist. This phase transition is very weak in the sense that its latent heat (per edge) is two orders of magnitude smaller than that of other well-known weak first-order phase transitions.
