内容説明
This the first volume of the proceedings of the International Workshop on Condensed Matter Theories published by a commercial publisher and of a series which is planned to appear anually. It is a tribute to the group of scientists who started this workshop as the Pan American Workshop on Conden sed Matter Theories in 1977 and helped to develop it to a significant annual international workshop. Many scientists' efforts have contributed to this important development and it is impossible to name all of them. But at least three persons are to be singled out: Professors Manuel de Llano and Angel Plastino who conceived the idea of the annual workshop and carried it for ward, and Professor John W. Clark who has been the prime driving force be hind it in recent years. The Workshop started in 1977 in Sao Paolo, Brazil, as the first Pan American Workshop on Condensed Matter Theories with the idea of bringing together scientists from the Western Hemisphere working in many different areas of Condensed Matter Theories for the purpose of cross-fertilization of ideas used in different areas and fostering collaborations among them. The next five Workshops were held at Trieste, Italy, in 1978; in Buenos Aires, Argentina, in 1979; in Caracas, Venezuela, in 1980; in Mexico City, Mexico, in 1981; and in St. Louis, Missouri, U. S. A., in 1982."

内容説明
The second volume of Condensed Matter Theories contains the proceedings of the 10th International Workshop held at Argonne National Laboratory, Argonne, IL, U.S.A. during the week of July 21, 1986. The workshop was attended by high-energy, nuclear and condensed-matter physicists as well as materials scientists. This diverse blend of participants was in keeping with the flavor of the previous workshops. This annual series of international workshops was"started in 1977 in Sao Paulo, Brazil. Subsequent'workshops were held in Trieste (Italy), Buenos Aires (Argentina), Caracas (Venezuela), Altenberg (West Germany), Granada (Spain), and San Francisco (U.S.A.). What began as a meeting of the physicists from the Western Hemisphere has expanded in the last three years into an international conference of scientists with diverse interests and backgrounds. This diversity has promoted a healthy exchange of ideas from different branches of physics and also fruitful interactions among the participants. The present volume is a continuation of the effort started last year when the invited papers from the 9th International Workshop were published by Plenum Press. Our only trepidation in organizing a book of this kind stemmed from the diversity of the material, which did not lend itself easily to well-defined topics. Still, the articles are loosely divided into eight categories, where the papers in each category have either a common theme or the same underlying technique.

内容説明
This book is the third volume in an approximately annual series which comprises the proceedings of the International Workshops on Condensed Matter Theories. The first of these meetings took place in 1977 in Sao Paulo, Brazil, and successive workshops have been held in Trieste, Italy (1978), Buenos Aires, Argentina (1979), Caracas, Venezuela (1980), Mexico City, Mexico (1981), St. Louis, USA (1982), Altenberg, Federal Republic of Germany (1983), Granada, Spain (1984), San Francisco, USA (1985), and Argonne, USA (1986). The present volume contains the proceedings of the Eleventh Workshop which took place in Qulu, Finland during the period 27 July - 1 August, 1987. The original motivation and the historical evolution of the series of Workshops have been amply described in the preface to the first volume in the present series. An important objective throughout has been to work against the ever-present trend for physics to fragment into increasingly narrow fields of specialisation, between which communication is difficult. The Workshops have traditionally sought to emphasise the unity of physics. By bringing together scientists working in many different areas of condensed matter theory, for the dual purpose of fostering collaborations between them and promoting the exchange of ideas between various disciplines, a common language has been exposed and developed. The Editor of the first volume in the series, F. B.

内容説明
This volume gathers the invited talks of the XIII International Work shop on Condensed Matter Theories which took place in Campos do Jordao near Sao Paulo, Brazil, August 6-12, 1989. It contains contributions in a wide variety of fields including neutral quantum and classical fluids, electronic systems, composite materials, plasmas, atoms, molecules and nuclei, and as this year's workshop reflected the natural preoccupation in materials science with its spectacular prospect for mankind, room tempera ture super-conductivity. All topics are treated from a common viewpoint: that of many-body physics, whether theoretical or simu1ational. Since the very first workshop, held at the prestigious Instituto de Fisica Teorica in Sao Paulo, and organized by the same organizer of the 1989 workshop, Professor Valdir Casaca Aguilera-Navarro, the meeting has taken place annually six times in Latin America, four in Europe and three in the United States. Its principal objective has been to innitiate and nurture collaborative research networks of scientists interested in the IDultidisciplinary aspects of many-body theory applied to problems in con densed-matter physics. Financial as well as moral support is gratefully appreciated by all: of the CLAF in Rio, the CNPq in Brasilia, the FAPESP and the FUNDUNESP in Sao Paulo, and the U.S. Army Research Office in Durham, NC, USA.

内容説明
This series on condensed matter theories provides a forum for advanced theoretical research in quantum many-body theory. The contributions are highly interdisciplinary, emphasizing common concerns among theorists who apply many-particle methods in such diverse areas as solid-state, low-temperature, statistical, nuclear, particle, and biological physics, as well as in quantum field theory, quantum information and the theory of complex systems. Each individual contribution is preceded by an extended introduction to the topic treated. Useful details not normally presented in journal articles can be found in this volume.

内容説明
The Thirty-First International Workshop on Condensed Matter Theories (CMT31) held in Bangkok focused on the many roles played by ab initio theory, modeling, and high-performance computing in condensed matter and materials science, providing a forum for the discussion of recent advances and exploration of new problems. Fifty-six invited papers were presented, of which 38 appear as chapters in this volume. Reports of recent results generated lively debate on two-dimensional electron systems, the metal-insulator transition, dilute magnetic semiconductors, effects of disorder, magnetoresistence phenomena, ferromagnetic stripes, quantum Hall systems, strongly correlated Fermi systems, superconductivity, dilute fermionic and bosonic gases, nanostructured materials, plasma instabilities, quantum fluid mixtures, and helium in reduced geometries.
