磁性量子相变

Magnetic quantum phase transitions

量子相变广泛存在于关联电子材料体系中,与非常规超导和奇异金属行为有着紧密的联系。近年来,人们对量子相变的认识正在不断深入,不同类型的量子相变相继被发现。揭示量子相变的普适分类,发展和完善量子相变理论,探索量子临界点附近的呈展量子态及其产生机理是当前量子相变研究的热点。文章简要介绍磁性量子相变的一些最新研究进展以及面临的挑战。

Zero-temperature quantum phase transitions,which are ubiquitous throughout correlated electron systems,exhibit a strong connection with both unconventional superconductivity and strange metal behaviors.Recently,a deeper understanding of quantum phase transitions has been achieved,and different types of quantum phase transitions have been found.Uncovering the universal classification for quantum phase transitions,developing theories of quantum phase transitions,and exploring the emergent quantum states and their mechanisms in the vicinity of a quantum critical point remains a major research focus.This review presents some recent research progress and challenges in the field of magnetic quantum phase transitions.
