项目摘要
TECHNICAL SUMMARY This award supports theoretical and computational research to improve the first-principles-based theoretical description of strongly correlated materials through the incorporation of quantum many-body theory methods like dynamical mean field theory and to investigate properties, ordered states, and associated phenomena of strongly correlated materials. The PI will develop many-body concepts analytical methods and computational techniques to investigate the properties of correlated metals insulators and superconductors. The PI will study the physical properties of Hunds metals such as the iron pnictides and chalcogenides. All these materials are "bad metals" at high temperatures. The PI will develop a theory of transport in a regime where materials are not well described by Fermi liquid theory. The PI will investigate the unusual thermoelectric properties of correlated insulators such as iron silicide and antimonide, in and out of equilibrium. In the long term, the PI envisions the construction of a framework for predicting and understanding the physical properties of correlated materials, building on the successes of the Dynamical Mean Field Theory. This framework would enable the computational design of materials with strongly correlated electron systems, starting from first principles. The PI plans to develop an interactive website which will serve as an archive of computationally intensive results for various materials. NONTECHNICAL SUMMARYThis award supports theoretical and computational research to improve materials-specific theoretical descriptions of materials in which electrons strongly interact with each other leading to strong correlations in electronic motion and unusual materials property and phenomena. Modern solid-state physics explains the physical properties of numerous materials, such as traditional metals, semiconductors, and insulators which provide the basis of our modern technological society. But materials with electrons derived from d- and f-electron shells tend to fall outside the scope of this theory and have remarkable properties. Examples include: iron pnictide materials which exhibit high temperature superconductivity where electrons flow in the absence of resistance, and iron silicide and iron antimonide which exhibit exceptionally large thermoelectricity where large temperature differences develop at different areas of the material when an electric field is applied. The PI will develop concepts, techniques, and computational tools to describe this class of materials and elucidate the origin of their remarkable properties The PI plans to develop an interactive website which will serve as an archive of computationally intensive results for various materials.
技术摘要该奖项支持理论和计算研究,通过结合动态平均场理论等量子多体理论方法来改进强相关材料的基于第一性原理的理论描述,并研究强相关材料的性质、有序态和相关现象。 PI 将开发多体概念分析方法和计算技术来研究相关金属绝缘体和超导体的特性。首席研究员将研究洪兹金属的物理性质,例如铁磷族化物和硫族化物。 所有这些材料在高温下都是“坏金属”。 PI 将在费米液体理论无法很好描述材料的情况下发展一种输运理论。 PI 将研究相关绝缘体(例如硅化铁和锑化物)在平衡状态和非平衡状态下的异常热电特性。从长远来看,PI 设想在动态平均场理论的成功基础上构建一个框架来预测和理解相关材料的物理特性。 该框架将从第一原理开始,实现具有强相关电子系统的材料的计算设计。 PI 计划开发一个交互式网站,作为各种材料的计算密集型结果的存档。 非技术摘要该奖项支持理论和计算研究,以改进材料特定的理论描述,其中电子彼此强烈相互作用,导致电子运动和不寻常的材料特性和现象之间的强相关性。 现代固态物理学解释了传统金属、半导体和绝缘体等众多材料的物理特性,这些材料为我们现代技术社会奠定了基础。但具有源自 d 和 f 电子壳层的电子的材料往往不属于该理论的范围,并且具有显着的特性。例子包括:铁磷化物材料,其表现出高温超导性,其中电子在没有电阻的情况下流动;以及铁硅化物和铁锑化物,其表现出异常大的热电性,其中当施加电场时,在材料的不同区域产生大的温差。 PI 将开发概念、技术和计算工具来描述此类材料并阐明其卓越特性的起源。PI 计划开发一个交互式网站,该网站将作为各种材料的计算密集型结果的存档。
