高温超导体中的无序理论

Theory of Intertwined Orders in High Temperature Superconductors

Eduardo Fradkin, Steven A. Kivelson, John M. Tranquada

摘要:

许多高度相关系统的电子相图,特别是铜氧化物高温超导体,是复杂的,许多不同的相出现类似的,有时相同的排序温度,即使材料的性能,如掺杂剂浓度,在很宽的范围内变化。这种复杂性有时被称为“竞争订单”。然而,由于这种关系是密切的,甚至可以导致新的物质相的存在,如假定的“对密度波”,一般的关系是更好地认为在“交织秩序。“我们选择性地分析了铜氧化物中的一些实验,这些实验表明,物理学的基本方面反映在多个顺序的交织中,而不仅仅是每个顺序本身的性质。我们还总结和批评了几个理论思想的起源和影响,这种复杂性。

英文摘要:

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.
