Kondo model
The Kondo model (sometimes referred to as the s-d model) is a model for a quantum impurity coupled to a large reservoir of noninteracting electrons. The quantum impurity is represented by a spin-1/2, which is coupled to a continuous band of noninteracting electrons by an antiferromagnetic exchange coupling, J. The Kondo model is used as a model for metals containing magnetic impurities, as well as quantum dot systems. where is a spin-1/2 operator representing the impurity, and is the local spin-density of the noninteracting band at the impurity site (
