铜氧化物高温超导体中各种有序电子态以及这些有序电子态与超导序相互纠缠的研究

近年以来随着实验技术的改进和实验精度的提高，大量的实验结果指出铜氧化物高温超导体在赝能隙区域内存在着各种各样的竞争有序电子态，例如电荷密度波、对密度波、向列序等，而这些反常的竞争有序电子态可能正是铜氧化物高温超导体在赝能隙区域内显示极为特殊的反常物理性质根本原因。我们在动能驱动的非常规超导电性理论框架下研究铜氧化物高温超导体在赝能隙区域内的这些竞争有序电子态反常的物理性质以及这些竞争有序电子态如何与超导态共存和相互纠缠，从而为铜氧化物高温超导体中出现的这些竞争有序电子态以及它们与超导态之间的相互关系提供一个可能的微观物理说明。

Although the experimental observations from different measurement techniques have confirmed the emergence of different ordered electronic states in the pseudogap phase of cuprate superconductors, such as charge density wave, pair density wave, nematic order, their full understanding is still a challenging issue. Within the framework of the kinetic-energy-driven superconductivity, the nature of these different ordered electronic states in the pseudogap phase of cuprate superconductors and of their intertwining with superconductivity are studied by taking into account the pseudogap effect. These studies are useful to examine the microscopic theory of the kinetic-energy-driven superconducting mechanism.
