Physics of transition metal oxides and correlated electronic systems

这项研究计划的目标是在基础水平上了解新型过渡金属氧化物中量子现象的性质，以及试图描述这些材料的各种理论物理模型。我们的研究工作将深入到奇异超导和量子磁性等主题--这些宏观量子现象源于有序和无序固体中相互作用电子的量子力学性质。特别是，这些行为不能用传统的金属基石理论来描述，事实上，上个世纪凝聚态理论的原理，特别是费米液体理论和巴丁-库珀-施里弗超导理论，当应用于这些新材料时是不成功的。作为理解这些材料的大型国家和国际努力的一部分，我们专注于为据信包含描述这些材料的关键成分的模型开发可靠的理论预测，并保持与无数令人兴奋的新实验观察的密切联系，这些实验观察提供了该领域目前享有的相当大的惯性。

The goal of this research program is to understand, at a fundamental level, the properties of quantum phenomena in novel transition metal oxides, and various theoretical-physics models that attempt to describe these materials. Our research efforts will delve into subjects such as exotic superconductivity and quantum magnetism - these macroscopic quantum phenomena arise from quantum mechanical properties of interacting electrons in both ordered and disordered solids. In particular, these behaviours cannot be described within conventional theories of metals - cornerstones and in fact tenets of condensed matter theory in the last century, notably Fermi liquid theory and the Bardeen-Cooper-Schrieffer theory of superconductivity, are unsuccessful when applied to these new materials. As part of a large national and international effort to understand these materials, we focus on developing reliable theoretical predictions for models that are believed to contain the key ingredients in describing these materials, as well as on maintaing close contact with the myriad of exciting new experimental observations that has provided the considerable inertia that this field now enjoys.
