高温超导体中的电子配对机制是高温超导机理研究中一个重要的课题.经过近30年的研究,人们已经逐步取得了磁性关联是导致高温超导体电子d-波配对驱动力的共识.但是如何从这一共识出发理解高温超导体的复杂物理性质,尤其是与欠掺杂区域的赝能隙现象相关联的一系列反常物理性质,仍然是一个重大的挑战.解决这个问题的关键在于理解强关联效应导致的高温超导体电子的巡游-局域二元性.

英文摘要：

The pairing mechanism of the high temperature superconductors is one of the most important issues in the study of the high temperature superconductivity. After the intensive investigation in the past three decades, it is now commonly accepted that the d-wave pairing in the high temperature superconductors is driven by the exchange of the antiferromagnetic spin fluctuation in the system. However, an open problem remains： how to understand the complex phase diagram of the high temperature superconductors, especially the anomalous behaviors related to the pseudogap phenomena in the underdoped regime. The key to the answer of this question lies in the local-itinerant dualism of the electron in these systems.
