Quantum impurity in a magnetic environment
arXiv:cond-mat/0304171 · doi:10.1023/B:JOSS.0000019819.67227.f8
Abstract
A unified perspective is given on a number of different problems involving the coupling of a localized quantum spin degree of freedom to the low energy excitations of an antiferromagnet, a spin glass, or a Kondo insulator. The problems are related to those in the class often referred to as "Bose Kondo".
