Schrieffer-Wolff transformation of Anderson Models

Schrieffer-Wolff transformation is one of the very important transformations in the study of quantum many body physics. It is used to arrive at the low energy effective hamiltonian of Quantum many-body hamiltonians, which are not generally analytically tractable. In this paper we give a pedagogical...

Summary:Schrieffer-Wolff transformation is one of the very important transformations in the study of quantum many body physics. It is used to arrive at the low energy effective hamiltonian of Quantum many-body hamiltonians, which are not generally analytically tractable. In this paper we give a pedagogical review of this transformation for Anderson Impurity model(SIAM) and its lattice generlaization called, the Periodic Anderson Model(PAM).
