This individual investigator award is to a professor at Stanford University for a project using angle-resolved photoemission spectroscopy (ARPES) to study complex materials with strongly interacting electrons. These materials have many remarkable properties, such as high temperature superconductivity. In addition, they provide the opportunity to discover and study novel fundamental phenomena and phases. ARPES has emerged as a major tool in advancing the understanding of these strongly interacting electron systems at the microscopic level. With the recent significant improvement in resolution and detection efficiency, ARPES has the promise to make greater contributions to the understanding of strongly interacting electron systems, in particular the oxides with novel properties from coupled charge, spin, orbital and lattice degrees of freedom. The objective of this project is to bring the experimental sophistication to a qualitatively higher level in order to address the most critical issues in the field, especially the issues related to high-temperature superconductivity. At the same time, the project will also function as an effective tool to educate and train graduate students and thus enlarge the scientific talent pool.%%%This individual investigator award is to a professor at Stanford University for a project concerned with the understanding of complex oxides that contain many novel phases and properties, including unconventional dielectric insulators and high-temperature superconductors that may lead to important applications. By directly measuring the motion of individual electrons using a sophisticated spectroscopy, this project tries to reveal the underlying microscopic principles that govern the fascinating properties manifested in these materials. This process will also train and educate graduate students and thus enlarge the scientific talent pool.

这个个人研究奖是给斯坦福大学的一位教授的，他的一个项目使用角分辨光电子能谱（ARPES）来研究具有强相互作用电子的复杂材料。 这些材料具有许多显著的性质，如高温超导性。 此外，它们还提供了发现和研究新的基本现象和阶段的机会。ARPES已经成为一个主要的工具，在推进这些强相互作用的电子系统在微观水平的理解。 随着近年来分辨率和探测效率的显著提高，ARPES有望为理解强相互作用电子系统，特别是具有耦合电荷、自旋、轨道和晶格自由度等新特性的氧化物做出更大贡献。 该项目的目标是将实验复杂性提高到更高的质量水平，以解决该领域中最关键的问题，特别是与高温超导性有关的问题。 同时，该项目也将成为教育和培养研究生的有效工具，从而扩大科学人才库。该个人研究奖授予斯坦福大学的一位教授，他的一个项目涉及对复杂氧化物的理解，这些氧化物包含许多新的相和特性，包括可能导致重要应用的非常规介电绝缘体和高温超导体。 通过使用复杂的光谱直接测量单个电子的运动，该项目试图揭示控制这些材料中表现出的迷人特性的潜在微观原理。 这一进程还将培养和教育研究生，从而扩大科学人才库。
