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.

这里提出的研究计划涉及复杂材料的电子性质的理论研究，如过渡金属氧化物，重原子元素材料（f-电子基），高温铜酸盐超导体和有机材料。含有多种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。控制这种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，人们已经知道，这些行为不仅仅是随机事件，不同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普遍性，这对随后的科学和技术发展至关重要。我主要感兴趣的是绝缘和金属磁性系统的新颖磁性和输运性质，以及这些系统中物质不同相之间的相变。
