This book is an introduction to the techniques of manybody quantum theory with a large number of applications to condensed matter physics. The basic idea of the book is to provide a selfcontained formulation of the theoretical framework without losing mathematical rigor, while at the same time providing physical motivation and examples. The examples are taken from applications in electron systems and transport theory. On the formal side, the book covers an introduction to second quantization, manybody Green's function, finite temperature Feynman diagrams and bosonization. The applications include traditional transport theory in bulk as well as mesoscopic systems, where both the LandauButtiker formalism and recent developments in correlated transport phenomena in mesoscopic systems and nanostructures are covered. Other topics include interacting electron gases, plasmons, electronphonon interactions, superconductivity and a final chapter on onedimensional systems where a detailed treatment of Luttinger liquid theory and bosonization techniques is given. Having grown out of a set of lecture notes, and containing many pedagogical exercises, this book is designed as a textbook for an advanced undergraduate or graduate course, and is also well suited for selfstudy.
