A large fraction of modern technology (computers, telecommunications, electronics in general) relies on the properties of electrons in solids. Depending on the behavior of electrons, solids can be metals, insulators, magnets, semiconductors, superconductors and so on. Our theoretical understanding of electrons in solids is based on quantum mechanics, but often within a simple, approximate model in which electrons do not interact very much with each other. This simple model is at fault in many interesting materials where the effects of electron-electron repulsion are strong. We say that electrons in such materials are "strongly correlated". I study theoretical models of strongly correlated electrons in solids, in the framework of quantum mechanics and with the help of powerful computers.

大量的现代技术（计算机，电信，电子设备）依赖于固体中电子的性质。根据电子的行为，固体可以是金属，绝缘子，磁铁，半导体，超导体等。我们对固体中电子的理论理解是基于量子力学的，但是通常在一个简单的近似模型中，其中电子相互作用并不相互作用。在许多有趣的材料中，这种简单的模型是错误的，在这些材料中，电子电子排斥的影响很强。我们说这些材料中的电子“密切相关”。我研究了固体，量子力学框架以及强大的计算机的固体中强相关电子的理论模型。
