Although the Standard Model of strong and electroweak interactions describesparticle physics phenomena up to the vector boson mass scale very well, it is in general believed that it is not the ultimate theory. The aim of this series of seminars was to initiate discussions between field theorists and phenomenologically oriented high energy physicists on the observable consequenses of the concept of SUSY. The subjects covered by the individual contributions include an introduction to the basic features of SUSY models, in particular the minimal supersymmetric Standard Model, followed by discussions of the theoretical predictions and experimental findings on the particle content and mass spectra, cosmological consequenses, indirect manifestations through quantum effects, radiative corrections in the supersymmetric Higgs sector, and the concept of dynamical electroweak symmetry breaking in the context ofSUSY. These topics are treated at a level appropriate for advanced students.However, the book should also be useful for teachers and researchers.

This comprehensive book on Nanoclusters comprises sixteen authoritative chapters written by leading researchers in the field. It provides insight into topics that are currently at the cutting edge of cluster science, with the main focus on metal and metal compound systems that are of particular interest in materials science, and also on aspects related to biology and medicine. While there are numerous books on clusters, the focus on clusters as a bridge across disciplines sets this book apart from others. Delivers cutting edge coverage of cluster science Covers a broad range of topics in physics, chemistry, and materials science Written by leading researchers in the field.

D. Bohm and B.J. Hiley

In The Undivided Universe, Professor David Bohm, one of the foremost scientific thinkers of the day and one of the most distinguished physicists of his generation, presents a radically different approach to quantum theory. With Basil Hiley, his co-author and long-time colleague, an interpretation of quantum theory is developed which gives a clear, intuitive understanding of its meaning and in which there is a coherent notion of the reality of the universe without assuming a fundamental role for the human observer. With the aid of new concepts such as active information together with non-locality, a comprehensive account of all the basic features of quantum theory is provided, including the relativistic domain and quantum field theory. The new approach is contrasted with other commonly accepted interpretations and it is shown that paradoxical or unsatisfactory features of the other interpretations, such as the wave-particle duality and the collapse of the wave function, do not arise. Finally, on the basis of the new interpretation, the authors make suggestions that go beyond current quantum theory and they indicate areas in which quantum theory may be expected to break down in a way that will allow for a test.

At what level of physical existence does "quantum behavior" begin? How does it develop from classical mechanics? This book addresses these questions and thereby sheds light on fundamental conceptual problems of quantum mechanics. Quantum-Classical Correspondence elucidates the problem by developing a procedure for quantizing stochastic systems (e.g. Brownian systems) described by Fokker-Planck equations. The logical consistency of the scheme is then verified by taking the classical limit of the equations of motion and corresponding physical quantities. Perhaps equally important, conceptual problems concerning the relationship between classical and quantum physics are identified and discussed. Physical scientists will find this an accessible entrée to an intriguing and thorny issue at the core of modern physics.
