Theory of Correlated Electron Systems

理论研究将集中在以电子相关为基础的材料上，重点是重费米子和高温超导体。本文将利用现象学技术和微观起源的基础研究来研究重费米子系统，重点研究超导序参量与交错磁化的耦合。对于高温超导体，将在光发射实验的理论基础上进行分析。变分蒙特卡罗技术将用于研究这两个系统中相关和无序之间的相互作用。理论研究将涉及两个非常重要的系统的基本问题：高温超导体和重费米子超导体。对这两种系统的深入研究将影响凝聚态物质和材料物理学的基本概念，但在商业领域也有潜在的重大回报。

Theoretical research will be conducted on materials for which electron correlations play a fundamental role, focusing on heavy fermion and high-temperature superconductors. The heavy fermion system will be attacked using both phenomenological techniques and fundamental studies of microscopic origins with an emphasis on the coupling of the superconducting order parameter with the staggered magnetization. For high-temperature superconductors, analysis will be conducted on the theoretical basis for photoemission experiments. Variational Monte Carlo techniques will be used to study the interplay between correlation and disorder in both of these systems. %%% Theoretical research will be undertaken on fundamental issues relating to two very important systems of current interest: high- temperature superconductors and heavy fermion superconductors. Insight into both of these systems will affect basic concepts of condensed matter and materials physics, yet has the potential to have significant payoff in the commercial arena.
