报告内容简介:

In this talk, using the cuprate high temperature superconductors as the best studied illustrative example, Prof. Steven Kivelson will discuss the question - Why are the phase diagrams of highly correlated electronic systems so complicated? In particular, multiple different phases appear 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, 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.
