5 PREFACE The present volume contains the texts of the invited talks delivered at the Sixth International Conference on Recent Progress in Many-Body Theories held in Arad, Israel during the period November The host institute was the Physics Department at the Ben Gurion University of the Negev. Beside the invited talks there have been also two poster sessions. The general format and style of the meeting followed closely those which had preceded it and evolved from the earlier conferences in the series: Trieste 1978, Oxtapec 1981, Altenberg 1983, San Francisco 1985 and Oulu The conferences in this series are intended to cover the broad spectrum of modem physics related to the many body problem. It starts on the smallest length scales in dealing with quark gluon plasmas and ends on the largest length scales in tackling many body problems in astrophysics. In between, it is concerned with nuclear physics, solid state physics, statistical mechanics, field theory, molecular dynamics, hydrodynamics, chaos, etc. Like in the Oulu conference, special emphasis has been put on recent developments in high Tc superconductivity. Beside the half day session devoted to it we have also organized an evening round table discussion on the future of the whole subject. Furthermore, a new, and in the opinion of the editor a very refreshing element which was absent in earlier conferences was the presentation of a few talks by experimentalists. Another aspect which the local organizing committee found worth presenting is concerned with many body aspects which are not directly related to traditional many body theories. Thus, we have dedicated sessions to localization which included also propagation of waves in disordered media, and a session to the rapidly developing field of mesoscopic systems. We have decided to organize the lectures in groups in such a way that each group is related to a special topic. This classification is somewhat artificial, but we found it very useful, especially for those who are interested in a certain part of the topics which have been presented. The main subjects covered in this conference and which are presented in this book are High T Superconductivity, Localization, Nuclear Physics, Mesoscopic Systems, Strongly Correlated Systems and Microscopic Approaches (including Quantum Fluids, Surface Structure, Deep Inelastic Scattering,and other topics). A special event which took place in this conference is the presentation of the Feenberg Medal Award to Prof. M. Kalos of Courant Institute and Cornell v

6 University. This medal is awarded each conference (starting from the San Francisco Conference at 1985) for outstanding achievements in the physics of many body problems. Prof. Kalos is then joining Prof. D. Pines from Urbana (recipient of the medal in 1985) and Prof. J. Clark of Washington University (recipient of the medal in 1987). At the height of our work for the preparation of the conference we were faced by the very sad event of the death of our conference secretary and colleague Dr. Aharon Lonke. The first session was preceded by a few words commemorating his life and scientific activity. I would like to thank all those who helped me organize this conference. They include the international advisory board - [N. Ashcroft, R. Bishop, C. Campbell, J. W. Clark, S. Fantoni, I. M. Khalatnikov, A. Kallio, H. Kummel. M. Ristig and D. Yoshioka.]' the local organizing committee [ O. Entin Wohlman, H. Gutfreund, Y. Imry, M. Kaveh and M. Revsen.] and our sponsors [The U.S Navy, the Technion, Bar Han University, Tel Aviv University, Ben Gurion University, the Weizmann Institute of Science, the Israeli Academy of Science, the Israeli Ministry of Research and Development and the Israeli Ministry of Tourism. Special thanks are directed to Mr. G. Neuman for suggesting and drawing the conference symbol. However, the warmest thanks must go to all the participants and the speakers without whom the conference and this volume would not have been established. Y.
