Toward an exact quantum many-body treatment of Kondo correlation in magnetic impurities.

The Kondo effect is a prototypical quantum phenomenon arising from the interaction between localized electrons in a magnetic impurity and itinerant electrons in a metallic host.

The Kondo effect is a prototypical quantum phenomenon arising from the interaction between localized electrons in a magnetic impurity and itinerant electrons in a metallic host. Although this phenomenon has served as the testing ground for quantum many-body methods for decades,…
