The electronic phase diagrams of many highly correlated systems, and in particular the cuprate high temperature superconductors, are complex, with many different phases appearing with similar-sometimes identical-ordering temperatures even as material properties, such as a dopant concentration, are varied over wide ranges. This complexity is sometimes referred to as "competing orders." However, since the relation is intimate, and can even lead to the existence of new phases of matter such as the putative "pair-density-wave," the general relation is better thought of in terms of "intertwined orders." We selectively analyze some of the experiments in the cuprates which suggest that essential aspects of the physics are reflected in the intertwining of multiple orders-not just in the nature of each order by itself. We also summarize and critique several theoretical ideas concerning the origin and implications of this complexity.

Functional Nanoscale Phase Separation and Intertwined Order in Quantum Complex Materials
纳米尺度的相分离(Phase Separation,简称纳米相分离)是高温超导体(High Temperature Superconductors,简称HTS)的重要组成部分。我们的研究结果表明,多尺度异质性是复杂材料中量子功能的重要组成部分。在这里,不同的结构单元之间的相互作用导致动态时空构象与相关的无序。因此,可视化的构象景观需要了解复杂物质的物理性质,并需要先进的方法,高精度的X射线测量的基础上。讨论了氧掺杂钙钛矿超导材料中纳米尺度下的动力学关联无序及其相关功能

Intertwined charge, spin, and pairing orders in doped iron ladders
受铁基梯形化合物实验研究进展的启发,我们研究了双腿梯形BaFe $_2$ S $_3$的掺杂双轨道哈伯德模型.利用{ \it ab initio}跳跃参数构造了该模型,并利用密度矩阵重整化群方法研究了其基态性质.我们发现,$(π,0)$磁有序半填充,铁磁梯级和反铁磁腿,成为不相称的空穴掺杂。此外,根据Hubbard $U$耦合的强度,其他磁模式,如$(0,π)$,也是稳定的。我们发现,两个空穴的结合能成为负的中间哈伯德相互作用强度,表明空穴配对。由于晶体场在轨道之间分裂,空穴主要驻留在一个轨道中,另一个轨道保持半填充。这类似于轨道选择性莫特态。紧密空穴对的形成随着空穴密度的增加而继续,只要磁序在一个方向上保持反铁磁。对对相关性的研究表明,轨道内自旋单重态通道的主导地位,而不是其他配对通道。虽然在一个范围内的空穴掺杂配对的相关性衰减缓慢,我们的结果也可以被解释为对应的电荷密度波对,最终的超导性的前体后,梯间耦合包括在内。这种相互交织的秩序的情况已经在铜酸盐中进行了广泛的讨论,我们的研究结果表明,类似的物理可能存在于梯形铁基超导体。最后,我们还表明,一个强大的洪德耦合需要配对发生。

Nematic quantum critical point without magnetism in FeSe1-xSx superconductors
反铁磁涨落的重要性在大多数非常规超导体中得到了广泛的承认。此外,铜酸盐和铁磷属元素化物经常表现出单向(单向)电子相关性,包括条纹和轨道顺序,其波动也可能对电子配对起关键作用。然而,这些相互关联与反铁磁或电荷序交织在一起,使我们无法确定相互关联波动的重要作用。这就要求新材料只有向列性,而没有竞争或共存的秩序。在这里,我们报告了FeSe $_{1-x}$ S $_{x}$超导体的系统弹性电阻测量,与其他铁基系列不同,该超导体表现出电子向列序,但不伴随反铁磁序。我们发现,随着硫含量$x$的增加,相变温度降低,而相变温度的波动强烈增强。在$x\approx0.17$附近,磁化率向绝对零度发散,揭示了一个量子临界点。这突出了FeSe $_{1-x}$ S $_{x}$作为适合于研究向列性对超导电性的影响的独特的掺杂体系。
