Schrieffer–Wolff transformation

The Schrieffer–Wolff transformation is a unitary transformation enabling one to obtain effective low energy physics from a given interacting and non-interacting Hamiltonians.[1] An important application of Schrieffer–Wolff method is the derivation of Kondo model from single impurity Anderson model, as first noticed by J.R. Schrieffer and P.A. Wolff.[2]
