Physics of transition metal oxides and correlated electronic systems

该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研究诸如奇异超导性和量子磁性等主题-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理论来描述--上个世纪凝聚态理论的基石和原则，特别是费米液体理论和巴丁-库珀-施里弗超导理论，在应用于这些新材料时是不成功的。作为一个大的国家和国际努力，以了解这些材料的一部分，我们专注于发展可靠的理论预测模型，被认为是包含在描述这些材料的关键成分，以及保持密切联系，无数令人兴奋的新的实验观察，提供了相当大的惯性，这一领域现在享有。

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.
