9704021 Jarell This is a renewal grant to support work on a theoretical study and numerical simulation of strongly correlated electron materials. The specific subjects include the high temperature superconductors, heavy fermion materials, non- Fermi liquid metals and exotic magnetic materials. Quantum Monte Carlo methods are combined with statistical inference to calculate the dynamical response of the models of these systems. The study has two main objectives: The first is to calculate, numerically and analytically, relevant properties of the model systems as accurately as possible. The second is to explore the non-perturbative features of these models, with the hope of finding new physical phenomena. %%% This grant continues the support of an active and enthusiastic young PI who is rapidly emerging as a leader in the general area of strongly correlated electrons. This is a class of materials which have wide ranging applications but whose properties are not as well understood, at least so far. The class of materials include the high temperature superconductors, heavy fermion materials, non-Fermi liquid metals and exotic magnetic materials. The proposed research program utilizes a variety of theoretical and numerical techniques and hopes to gain insight in to the observed properties as well as discover new physical phenomena. ***

9704021 Jarell这是一个更新补助金，以支持强相关电子材料的理论研究和数值模拟工作。 具体研究内容包括高温超导体、重费米子材料、非费米子液态金属和奇异磁性材料。 量子蒙特卡罗方法与统计推断相结合，计算这些系统的模型的动态响应。 这项研究有两个主要目标：第一是计算，数值和分析，尽可能准确地模型系统的相关属性。 第二是探索这些模型的非微扰特性，以期发现新的物理现象。 %这项赠款继续支持一个积极和热情的年轻PI谁是迅速成为强关联电子的一般领域的领导者。 这是一类具有广泛应用的材料，但至少到目前为止，其性质还没有得到很好的理解。 这类材料包括高温超导体、重费米子材料、非费米子液态金属和奇异磁性材料。 拟议的研究计划利用各种理论和数值技术，并希望获得洞察观察到的属性，以及发现新的物理现象。 ***
