Density matrix formulation for quantum renormalization groups.

Physical Review Letters, 1992
A generalization of the numerical renormalization-group procedure used first by Wilson for the Kondo problem is presented. It is shown that this formulation is optimal in a certain sense.

The renormalization group: Critical phenomena and the Kondo problem

, 1975
This review covers several topics involving renormalization group ideas. The solution of the $s$-wave Kondo Hamiltonian, describing a single magnetic impurity in a nonmagnetic metal, is explained in detail. See Secs. VII-IX. "Block spin" methods, applied

Density-matrix algorithms for quantum renormalization groups.

Physical Review B (Condensed Matter), 1993
A formulation of numerical real-space renormalization groups for quantum many-body problems is presented and several algorithms utilizing this formulation are outlined.
