论文摘要
我们探讨了由三色费米子组成的一维气体的零温度相图，该气体在本地及其下一个邻居相互作用。使用密度矩阵重新归一化的组方法并考虑三分之一的填充，我们表征了几个参数值的基态，找到了不同的阶段，即：相位分离，自旋密度波，配对相，金属相，两个不同的电荷密度波和不可观的电荷状态。我们表明，冯·诺伊曼（Von Neumann）块熵和保真度易感性对于估计各个相之间的边界很有用。
We explore the zero-temperature phase diagram of a one-dimensional gas composed of three-color fermions, which interact locally and with their next neighbors. Using the density matrix renormalization group method and considering one-third filling, we characterize the ground state for several values of the parameters, finding diverse phases, namely: phase separation, spin density wave, pairing phase, a metallic phase, two different charge-density waves, and a non-separable state with modulation of charge. We show that the von Neumann block entropy and the fidelity susceptibility are useful for estimating the borders between the phases.
