R. McWeeny - Böcker

These papers are a selection of those presented at the first European Workshop on Quantum Systems in Chemistry and Physics, held at San Miniato, near Pisa, Italy, in April 1996, which brought together leading experts in theoretical chemistry and molecular physics with an interest in the quantum-mechanical many-body problem. The various contributions embrace topics such as density matrices and density functional theory, relativistic formulations, electron correlation, valence theory, nuclear motion, response theory, condensed matter, and chemical reactions.

This is one of two volumes which together comprise 40 papers coming from the most outstanding contributions to the third European Quantum Systems in Chemistry and Physics Workshop held in Granada, Spain (1997). These books cover a spectrum of scientific research from quantum-mechanical many-body methods to important applications and computational developments, and from atoms and molecules to condensed matter. The first volume is subtitled "Basic Problems and Model Systems", and includes the following topics: density matrices and density functionals, electron correlation effects, relativistic formulations, valence theory, and nuclear motions. The second volume is subtitled "Advanced Problems and Complex Systems" and covers the following topics: response theory, condensed matter, reactive collisions and chemical reactions and computational chemistry and physics.

This is one of two volumes which together comprise about 40 papers coming from the most outstanding contributions to the fourth European Quantum Systems in Chemistry and Physics workshop held in Marly, France, in 1999. These books cover a broad spectrum of scientific research work from quantum-mechanical many-body methods to important applications and computational developments, and from atoms and molecules to condensed matter. The first volume is subtitled "Basic Problems and Model Systems", which includes the following topics: density matrices and density functionals, electron correlation effects, relativistic formulations and effects, valence theory and nuclear motion. The second volume is subtitled "Advanced Problems and Complex Systems" and covers the following topics: response theory, reactive collisions and chemical reactions and condensed matter.

These two volumes collect thirty-eight selected papers from the scientific contributions presented at the Fourth European Workshop on Quantum Systems in Chemistry and Physics (QSCP-IV), held in Marly-le-Roi (France) in April 22-27, 1999, A total ofone hundred and fifteen scientists attended the workshop, 99 from Europe and 16 from the rest ofthe world. They discussed the state of the art, new trends, and future evolution of the methods and applications. The workshop was held in the old town of Marly-le-Roi, which lies to the West of Paris between the historic centres of Saint-Germain-en-Laye and Versailles. Participants were housed at the National Youth Institute, where over sixty lectures were given by l- ding members ofthe scientific community; in addition, over sixty posters were presented in two very animated sessions. We are grateful to the oral speakers and to the poster p- senters for making the workshop such an stimulating experience. The social programme was also memorable - and notjust for the closing banquet, which was held at the French Senate House. We are sure that participants will long remember their visit to the 'Musée des Antiquités Nationales': created by Napoleon III at the birthplace ofLouis XIV, this museum boasts one ofthe world finest collections ofarcheological artifacts. The Marly-le-Roi workshop followed the format established at the three previous meetings, organized by Prof.
