Theory of novel quantum phases and transitions

这里提出的研究计划涉及复杂材料的电子特性的理论研究，如过渡金属氧化物，重原子元素（f电子基）材料，高温铜超导体和有机材料。含有许多原子元素的复杂材料在电子性质上往往表现出意想不到的行为。控制这些不寻常的行为是设计具有先进性能的新材料的关键。另一方面，我们已经知道这些行为不是随机事件，在不同的材料之间出现了一定的普遍性。我研究的主要目的是了解这些材料的新兴普遍性，这对科学和技术的后续发展至关重要。我主要对绝缘和金属磁系统的新型磁性和输运性质以及这些系统中不同相物质之间的相变感兴趣。

The research program proposed here concerns theoretical studies of electronic properties of complex materials such as transition metal oxides, materials with heavy atomic elements (f-electron-based), high temperature cuprate superconductors, and organic materials. Complex materials with many atomic elements often show unexpected behaviors in electronic properties. Controlling such unusual behaviors is the key for the design of new materials with advanced properties. On the other hand, it has been known that these behaviors are not just random events and certain universality among different materials emerges. The primary objective of my research is to understand the emergent universality that will be extremely important for subsequent development of science and technology of these materials. I am mainly interested in novel magnetic and transport properties of insulating and metallic magnetic systems and phase transitions between different phases of matter in those systems.
