论文摘要
我们比较了通过集群动态均值场理论获得的电子绿色功能的极点结构与分数化对密度波的结果的结果。在超导阶段，我们可以在具有超导和电荷顺序共存的状态下考虑该系统。以类似于S. Sakai等人（2016）的先前提出的“隐藏特色”模型的方式编写绿色的功能，从而导致了自我能源的类似的极点结构。配对密度波顺序的分数还将伪阶段描述为超导和电荷顺序波动的叠加。考虑到颗粒粒子和粒子孔对的现象学寿命会导致与数值结果相匹配的电子光谱函数。
We compare the pole structure of the electronic Green's function obtained by Cluster Dynamical Mean Field Theory to the results from the fractionalized Pair Density Wave idea. In the superconducting phase, we can consider the system in a state with coexistence of Superconducting and Charge order. Writing the Green's function in a way analogous to the previously proposed "hidden-fermions" model from S. Sakai et al (2016) leads to a similar pole structure for the self-energy. The fractionalization of the Pair Density Wave order also describes the pseudogap phase as a superposition of superconducting and charge order fluctuations. Considering a phenomenological lifetime for the particle-particle and particle-hole pairs leads to an electronic spectral function that matches the numerical results.
