论文摘要
我们研究了$ \ mathbb {z} _3 $ -fock parafermions的紧密绑定模型，带有单粒子和成对的术语。相图具有四个不同的阶段：一个间隙阶段，中央电荷$ C = 2 $的无间隙相位，以及两个带中央电荷$ C = 1 $的无间隙阶段。我们通过分析能量差距，纠缠熵和不同的相关函数来表征每个阶段。数值模拟与分析论点相辅相成。
We study a tight binding model of $\mathbb{Z}_3$-Fock parafermions with single-particle and pair-hopping terms. The phase diagram has four different phases: a gapped phase, a gapless phase with central charge $c=2$, and two gapless phases with central charge $c=1$. We characterise each phase by analysing the energy gap, entanglement entropy and different correlation functions. The numerical simulations are complemented by analytical arguments.
