Publisher's Synopsis
This advanced text/reference presents the quantum theory of systems having many degrees of freedom, either because the systems contain many particles, or because of the possibility of particle creation or annihilation, or both. Theoretical techniques begin at the second quantization and the elements of quantum field theory, including pairing and tunneling, leading to diagrammatic methods for the many-body problem and for scattering theory. The presentation is self-contained and includes many examples and problems.
