This is the third volume (the first two volumes are Progress in Nonequilibrium Green's Functions , M. Bonitz (ed.) and Progress in Nonequilibrium Green's Functions II , M. Bonitz and D. Semkat (eds.), which were published by World Scientific (Singapore), in 2000 and 2003, respectively, (ISBN 981-02-4218-2 and ISBN 981-238-271-2).) of articles on the theory of Nonequilibrium Green's functions (NGF) and their modern applications in various fields. The refereed papers in this volume are based on talks and posters presented at the interdisciplinary conference Progress in Nonequilibrium Green's Functions III which was held in August 2005 at Kiel University, Germany. The conference was attended by about 70 scientists working in a variety of fields of theoretical physics, including plasma physics, solid state theory, semiconductor optics and transport, nanostructures, nuclear matter and high energy physics. Compared to the previous conferences, new topics were covered, such as transport theory for molecular systems, combinations of NGF with (time-dependent) density functional theory or dynamical mean field theory. This reflects modern developments in many-body theory. As with the two previous volumes, this one, hopefully, will be a valuable and stimulating reference for students and researchers from various fields. In contrast to the previous volumes, this one appears as a volume of Journal of Physics: Conference Series . This option was chosen as Journal of Physics: Conference Series offers free access to the online version which also contains color figures. This, hopefully, will increase the distribution of the articles to the scientific community. This conference would not have been possible without the generous financial support from the Deutsche Forschungsgemeinschaft (DFG) and without help from many people. We are particularly grateful to Andrea Fromm, Fanny Geisler and Doris Schulz from the local organizating committee in Kiel and Wolf Dietrich Kraeft (Rostock) for assistence in the final editing of the papers.
This is the fourth volume1 of articles on the theory of Nonequilibrium Green's functions (NEGF) and their modern application in various fields such as plasma physics, semiconductor physics, molecular electronics and high energy physics. It contains 23 articles written by experts in many-body theory and quantum transport who summarize recent progress in their respective area of research. The articles are based on talks given at the interdisciplinary conference Progress in Nonequilibrium Green's functions IV which was held 17–21 August 2009 at the University of Glasgow, Scotland. This conference continues the tradition of the previous meetings which started in 1999 and which aimed at an informal exchange across field boundaries. The previous meetings and the earlier proceedings proved to be very stimulating not only for young researchers but also for experienced scientists, and we are convinced that this fourth volume will be as successful as the previous ones. As before, this volume includes only extended review-type papers which are written in a way that they are understandable to a broad interdisciplinary audience. All papers published in this volume of Journal of Physics: Conference Series have been peer reviewed through processes administrated by the Editors assuring highest scientific standards. In the review process some papers were substantially revised and improved and some were rejected. This conference would not have been possible without the remarkable work of the local organizing team around John Barker and Scott Roy and the generous financial support from the University of Glasgow and the Deutsche Forschungsgemeinschaft via SFB-Transregio 24.

Abstract In quantum statistics based on many-body Green’s functions, the effective medium is represented by the selfenergy. This book aims to discuss the selfenergy from this point of view. The knowledge of the exact selfenergy is equivalent to the knowledge of the exact correlation function from which one can evaluate any single-particle observable. Complete interpretations of the selfenergy are as rich as the properties of the many-body systems. It will be shown that classical features are helpful to understand the selfenergy, but in many cases we have to include additional aspects describing the internal dynamics of the interaction. The inductive presentation introduces the concept of Ludwig Boltzmann to describe correlations by the scattering of many particles from elementary principles up to refined approximations of many-body quantum systems. The ultimate goal is to contribute to the understanding of the time-dependent formation of correlations. Within this book an up-to-date most simple formalism of nonequilibrium Green’s functions is presented to cover different applications ranging from solid state physics (impurity scattering, semiconductor, superconductivity, Bose–Einstein condensation, spin-orbit coupled systems), plasma physics (screening, transport in magnetic fields), cold atoms in optical lattices up to nuclear reactions (heavy-ion collisions). Both possibilities are provided, to learn the quantum kinetic theory in terms of Green’s functions from the basics using experiences with phenomena, and experienced researchers can find a framework to develop and to apply the quantum many-body theory straight to versatile phenomena.
This book presents an up-to-date formalism of non-equilibrium Green's functions covering different applications ranging from solid state physics, plasma physics, cold atoms in optical lattices up to relativistic transport and heavy ion collisions. Within the Green's function formalism, the basic sets of equations for these diverse systems are similar, and approximations developed in one field can be adapted to another field. The central object is the self-energy which includes all non-trivial aspects of the system dynamics. The focus is therefore on microscopic processes starting from elementary principles for classical gases and the complementary picture of a single quantum particle in a random potential. This provides an intuitive picture of the interaction of a particle with the medium formed by other particles, on which the Green's function is built on.
