标题： Quantum impurity models from conformal field theory

摘要： 局部磁矩与巡游电子之间的耦合呈现出丰富的物理现象。 某些量子杂质系统的低能物理可以用共形场理论（CFT）来描述。 在本文中，我们构建了一类精确可解的模型，其基态由CFT关联函数给出，从而进一步加强了量子杂质模型与CFT之间的联系。 这里开发的方法完全是分析性的，可以应用于具有任意颜色数和多个杂质的费米子。 进行数值计算以表征我们模型的某些方面，这些方面我们没有分析结果。 显示英文摘要

摘要： The coupling between localized magnetic moments and itinerant electrons presents a plethora of interesting physics. The low-energy physics of some quantum impurity systems can be described using conformal field theory (CFT). In this paper, the connection between quantum impurity models and CFT is further strengthened as we construct a class of exactly solvable models with ground states given by CFT correlators. The method developed here is completely analytical and can be applied to fermions with an arbitrary number of colors and multiple impurities. Numerical calculations are performed to characterize certain aspects of our models for which we do not have analytical results.
