Our efforts are directed at some of the difficult quantum many-body problems that lie at the heart of contemporary condensed matter physics. My students and I have expertise in numerical approaches and a particular focus on systems of strongly interacting electrons. Much of our work is in the areas of Kondo physics and quantum magnetism. We're interested in the fate of localized electrons (spins) in a material environment, and we investigate what kinds of exotic ground states can be stabilized with various models and what kinds of quantum transitions between phases are possible.

我们的努力是针对一些困难的量子多体问题，在当代凝聚态物理学的核心。我和我的学生在数值方法方面有专长，特别关注强相互作用的电子系统。我们的大部分工作是在近藤物理学和量子磁学领域。我们对材料环境中局域电子（自旋）的命运感兴趣，我们研究了什么样的奇异基态可以用各种模型稳定，以及什么样的相位之间的量子跃迁是可能的。
