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. Michael Bonitz and Karsten Balzer Kiel, February 2010 1 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). The third volume Progress in Nonequilibrium Green's functions III M Bonitz and A Filinov (eds) was published in Journal of Physics: Conference Series, volume 35 (2006).

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.

Langreth, a list of the conference participants, a complete list of the conference talks and posters and several photographs taken during the conference. ) The fifth interdisciplinary conference 'Progress in Nonequilibrium Green's Functions' (PNGF5) was held at the University of Jyväskylä, Finland, on 27--31 August 2012. The conference continued the successful tradition of its predecessors (Rostock 1999, Dresden 2002, Kiel 2005 and Glasgow 2009) to bring together different communities for an interdisciplinary exchange of recent results and theoretical concepts. The conference focused on recent developments, current challenges and future perspectives in nonequilibrium Green's functions theory in various fields of physics but included also other many-body methods. Roughly 20 invited talks were given by some of the top scientists in the field, accompanied by 10 contributed talks. (Slides of several presentations can be found online at www.jyu.fi/physics/pngf5 .) Also a poster session was set up to enhance scientific discussions, building up new collaborations and enriching views and ideas. As at the previous meetings, the atmosphere was interactive and stimulating, benefitting both experienced scientists and young researchers and students. The present volume contains 14 articles based on works presented at this conference. The articles partly have review character so they should be of use for an interdisciplinary community working or interested in nonequilibrium Green's functions. All papers were refereed according to high scientific standards. The conference would not have been possible without financial support from the Federation of Finnish Learned Societies, Finnish Academy of Science and Letters and Nanoscience Center of the university of Jyväskylä which are greatly acknowledged. The local organizing committee is also grateful to the administration personnel, Marjut Hilska and Riitta-Liisa Kuittinen, for assistance. We further thank professor Antti-Pekka Jauho for invaluable help and advice during the organization of the conference. The editors of the present conference proceedings acknowledge the authors for their excellent papers and all the referees for participating in a thorough peer-reviewing of the manuscripts. Finally, it is our pleasure to announce that the sixth conference 'Progress in Nonequilibrium Green's Functions' (PNGF6) will be held in August 2015 at the University of Lund, Sweden.

Quantum many-body theory as a discipline in its own right dates largely from the 1950's. It has developed since then to its current position as one of the cornerstones of modern theoretical physics. The field remains vibrant and active, vigorous and exciting. Indeed, its successes and importance were vividly illustrated prior to the conference by the sharing of the 1998 Nobel Prizes in both Physics and Chemistry by three many-body theorists. Two of those Nobel laureates, Walter Kohn and Bob Laughlin, delivered invited lectures at this meeting, the tenth in the series of International Conferences on Recent Progress in Many-Body Theories. This series is universally recognized as being the premier series of meetings on this subject, and its proceedings have always summarized the current state of the art through the lectures of its leading practitioners. The present volume is no exception. A major aim of this conference series has been to foster the exchange of ideas between physicists working in all the diverse fields of application of quantum many-body theory. These include nuclear and subnuclear physics, quantum fluids, strongly correlated electronic systems, and low-dimensional condensed-matter systems and materials. All of these fields and others are represented in the present volume. Other topical themes covered include density functional theory and its applications to nuclear and electronic systems, quantum dots and chaos, and trapped Bose?Einstein condensates. Through this breadth of applications the reader will get a clear illustration of the power of the tools of modern microscopic quantum many-body theory, and their usefulness both in achieving a commonality of approach and understanding, and in transferring powerful ideas from one field to another.

The present volume contains the texts of the invited talks delivered at the Fifth International Conference on Recent Progress in Many-Body Theories held in Oulu, Finland during the period 3-8 August 1987. The general format and style of the meeting followed closely those which had evolved from the earlier conferences in the series: Trieste 1978, Oaxtepec 1981, Altenberg 1983 and San Francisco 1985. Thus, the conferences in this series are in tended, as far as is practicable, to cover in a broad and balanced fashion both the entire spectrum of theoretical tools developed to tackle the quan tum many-body problem, and their major fields of· application. One of the major aims of the series is to foster the exchange of ideas and techniques among physicists working in such diverse areas of application of many-body theories as nucleon-nucleon interactions, nuclear physics, astronomy, atomic and molecular physics, quantum chemistry, quantum fluids and plasmas, and solid-state and condensed matter physics. A special feature of the present meeting however was that particular attention was paid in the programme to such topics of current interest in solid-state physics as high-temperature superconductors, heavy fermions, the quantum Hall effect, and disorder. A panel discussion was also organised during the conference, under the chair manship of N. W. Ashcroft, to consider the latest developments in the extreme ly rapidly growing field of high-T superconductors.
