Simulations of Strongly Correlated Materials

计算模拟和研究将在强关联的电子系统上进行。这些系统的例子包括高温超导体、重费米子材料和磁性材料。量子蒙特卡罗技术将与统计推断方法相结合，使我们能够模拟这些系统的动态响应。此外，还将采用量子蒙特卡罗和分析技术相结合的方法。这项研究的一个目标是从实验和理论上更准确地计算模型系统的相关性质。另一个目标是探索这些模型的非微扰区，以便预测新的物理现象。%强关联多体系统，如高温超导体和磁性金属，不适用于微扰理论等常用的理论方法。因此，由于缺乏分析方法，计算模拟对于理解这些系统所涉及的物理变得越来越重要。这笔赠款将使用各种技术进行模拟，以评估这些技术，并深入了解样本强关联系统的基本物理。

Computational simulations and research will be conducted on strongly correlated electronic systems. Examples of these systems include high temperature superconductors, heavy Fermion materials and magnetic materials. Quantum Monte Carlo techniques will be combined with methods of statistical inference to allow us to simulate the dynamical response of these systems. In addition, methods which combine quantum Monte Carlo and analytical techniques will be employed. One objective of the research is to calculate experimentally and theoretically relevant properties of model systems more accurately than heretofore possible. Another objective is to explore the non-perturbative regions of these models in order to predict new physical phenomena. %%% Strongly correlated many-body systems such as high temperature superconductors and magnetic metals are not amenable to the usual theoretical techniques such as perturbation theory. Consequently, because of the absence of analytical methods computational simulations become increasingly important to understand the physics involved with these systems. This grant will conduct simulations using a variety of techniques in order to assess the techniques and to gain insight into the underlying physics for sample strongly correlated systems.
