✦ Synopsis

Bosonization is an important technique that represents one of the most powerful nonperturbative approaches to many-body systems currently available. The first part of this book examines its technical aspects, including one dimensional fermions, the Gaussian model, the structure of Hilbert space in conformal theories, Bose-Einstein condensation in two dimensions, non-Abelian bosonization, and the Ising and WZNW models. The second part discusses applications of the bosonization technique to realistic models including the Tomonaga-Luttinger liquid, spin liquids in one dimension and the spin-1/2 Heisenberg chain with alternating exchange. The third part addresses the problems of quantum impurities. Chapters cover potential scattering, the x-ray edge problem, impurities in Tomonaga-Luttinger liquids and the multi-channel Kondo problem. This excellent reference will interest researchers and graduate students working in theoretical physics and field theory.

This research monograph offers an introduction to advanced quantum field theoretical techniques for many-particle systems beyond perturbation theory. Several schemes for resummation of the Feynman diagrams are described. The resulting approximations are especially well suited for strongly correlated
