High-temperature superconductivity in doped Mott insulators such as the cuprates contradicts the conventional wisdom that electron repulsion is det-rimental to superconductivity. Because doped fullerene conductors are also strongly correlated, the recent discovery of high

We present a concise, but systematic, review of the ergodicity issue in strongly correlated systems. After giving a brief historical overview, we analyze the issue within the Green’s function formalism by means of the equations of motion approach. By means of this analysis, we are able

This volume provides a detailed account of bosonization. This important technique represents one of the most powerful nonperturbative approaches to many-body systems currently available. The first part of the book examines the technical aspects of bosonization. Topics include 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 presents 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 alternative 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 book will be an excellent reference for researchers and graduate students working in theoretical physics, condensed matter physics and field theory.

This thesis considers various aspects of the interplay between superconductivity and magnetism in strongly correlated electron systems. Chapter 2 studies the effects of weak translational symmetry breaking on the quasiparticle spectrum of a d-wave superconductor. A general formalism is developed

Abstract. Lectures deal with the theory of electronic transport, in particular with the electrical conductivity, in systems dominated by strong electron-electron repulsion. The concept of charge stiffness is introduced to distinguish conductors and insulators at T = 0, but as well usual resistors

After reviewing briefly the basic strategy of analyzing the RHIC data, recent lattice results of the non-pertubative/strong-coupling aspects of quark-gluon plasma probed primarily by the heavy quarks are presented. In particular, free energies of static quarks in various color channels, the Debye
