Standard textbooks on the many-body problem do not include a wealth
of valuable experimental data, in particular recent results from
direct knockout reactions, which are directly related to the
single-particle propagator in many-body theory. In this
indispensable book, the comparison with experimental data is
incorporated from the start, making the abstract concept of
propagators vivid and comprehensible. The discussion of numerical
calculations using propagators or Green's functions, also absent
from current textbooks, is presented in this book. Much of the
material has been tested in the classroom and the introductory
chapters allow a seamless connection with a one-year graduate
course in quantum mechanics. While the majority of books on
many-body theory deal with the subject from the viewpoint of
condensed matter physics, this book also emphasizes finite systems
and should be of considerable interest to researchers in nuclear,
atomic, and molecular physics. A unified treatment of many
different many-body systems is presented using the approach of
self-consistent Green's functions. Several topics, not available in
other books, in particular the description of atomic Bose-Einstein
condensates, have been included. The coverage proceeds in a
systematic way from elementary concepts, such as second
quantization and mean-field properties, to a more advanced but
self-contained presentation of the physics of atoms, molecules,
nuclei, nuclear and neutron matter, electron gas, quantum liquids,
atomic Bose-Einstein and fermion condensates, and pairing
correlations in finite and infinite systems.
