QUANTUM FIELD THEORY OF MANY-BODY SYSTEMS

For most of the last century, condensed matter physics has been dominated by band theory and Landau's symmetry breaking theory. In the last twenty years, however, there has been the emergence of a new paradigm associated with fractionalization, topological order, emergent gauge bosons and fermions, and string condensation. These new physical concepts are so fundamental that they may even influence our understanding of the origin of light and electrons in the universe. This book is a pedagogical and systematic introduction to the new concepts and quantum field theoretical methods in condensed matter physics. It discusses many basic notions in theoretical physics, which underlie physical phenomena in nature, including a notion that unifies light and electrons. Topics covered are dissipative quantum systems, boson condensation, symmetry breaking and gapless excitations, phase transitions, Fermi liquids, spin density wave states, Fermi and fractional statistics, quantum Hall effects, topological/quantum order, spin liquid and string condensation. Methods discussed include the path integral, Green's functions, mean-field theory, effective theory, renormalization group, bosonization in one- and higher dimensions, non-linear sigma-model, quantum gauge theory, dualities, slave-boson theory, and exactly soluble models beyond one-dimension. This book is aimed at bringing students to the frontiers of research in condensed matter physics.

Based on a two-semester course held at the University of Heidelberg, Germany, this book provides an adequate resource for the lecturer and the student. The contents are primarily aimed at graduate students who wish to learn about the fundamental concepts behind constructing a Relativistic Quantum Theory of particles and fields. So it provides a comprehensive foundation for the extension to Quantum Chromodynamics and Weak Interactions, that are not included in this book. Contents: The Principles of Quantum Physics Lorentz Group and Hilbert Space Search for a Relativistic Wave Equation The Dirac Equation The Free Maxwell Field Quantum Mechanics of Dirac Particles Second Quantization Canonical Quantization Global Symmetries and Conservation Laws The Scattering Matrix Perturbation Theory Parametric Representation of a General Diagram Functional Methods Dyson–Schwinger Equation Regularization of Feynman Diagrams Renormalization Broken Scale Invariance and Callan–Symanzik Equation Renormalization Group Spontaneous Symmetry Breaking Effective Potentials
