项目摘要
We study the mechanisms of anomalous electronic properties of transition-metal oxides with hollandite-type crystal structure. We use the first-principles electronic structure calculations based on the density functional theory as well as the model calculations based on the variational cluster approximation and density-matrix renormalization group method. We in particular clarify the origin of the quasi-one-dimensional electronic state of ruthenium oxide, mechanism of the perfect ferromagnetism and metal-insulator transition in chromium oxide, and mechanism of the formation of the superatomic crystal in molybdenum oxide.
我们研究具有荷兰石型晶体结构的过渡金属氧化物异常电子性能的机制。我们基于密度功能理论以及基于变异群集近似和密度 - 矩阵重新归一化组方法的第一原理电子结构计算以及模型计算。我们特别阐明了氧化丁烯二氮的准二维电子状态的起源,氧化铬中的完美铁磁性和金属绝缘体转变的机制以及氧化钼中超原晶体形成的机制。
