There are many excellent books on quantum theory from which one can learn to compute energy levels, transition rates, cross sections, etc. The theoretical rules given in these books are routinely used by physicists to compute observable quantities. Their predictions can then be compared with experimental data. There is no fundamental disagreement among physicists on how to use the theory for these practical purposes. However, there are profound differences in their opinions on the ontological meaning of quantum theory. The purpose of this book is to clarify the conceptual meaning of quantum theory, and to explain some of the mathematical methods which it utilizes. This text is not concerned with specialized topics such as atomic structure, or strong or weak interactions, but with the very foundations of the theory. This is not, however, a book on the philosophy of science. The approach is pragmatic and strictly instrumentalist. This attitude will undoubtedly antagonize some readers, but it has its own logic: quantum phenomena do not occur in a Hilbert space, they occur in a laboratory.

If the carriers of information are governed by quantum mechanics, new principles for information processing apply. This graduate textbook introduces the underlying mathematical theory for quantum communication, computation and cryptography. A focus lies on the concept on quantum channels and understanding figures of merit, s.a. fidelities and entropies in the quantum world. Instructive problems and solutions help to dive into the formalism.

Quantum Mechanics: Concepts and Applications provides a clear, balanced and modern introduction to the subject. Written with the student’s background and ability in mind the book takes an innovative approach to quantum mechanics by combining the essential elements of the theory with the practical applications: it is therefore both a textbook and a problem solving book in one self–contained volume. Carefully structured, the book starts with the experimental basis of quantum mechanics and then discusses its mathematical tools. Subsequent chapters cover the formal foundations of the subject, the exact solutions of the Schrödinger equation for one and three dimensional potentials, time–independent and time–dependent approximation methods, and finally, the theory of scattering. The text is richly illustrated throughout with many worked examples and numerous problems with step–by–step solutions designed to help the reader master the machinery of quantum mechanics. The new edition has been completely updated and a solutions manual is available on request. Suitable for senior undergradutate courses and graduate courses.

This volume contains the proceedings of a symposium held in honour of Jean-Pierre Vigier in Toronto, Canada, in August 1995. It encompasses many areas in which he has been active over the years, such as stochastic interpretations of quantum mechanics, particle physics and electromagnetic theory. The papers have been loosely ordered in the following categories: ideas about the nature of light and photons; electrodynamics; the formulation and interpretation of quantum mechanics; and aspects of relativity theory. Some of the papers presented deal with alternate interpretations of quantum phenomena in the tradition of Vigier, Bohm et al. The current experimental situation allows for the first time for individual quantum events to be studied, and this opens possibilities for challenges to the orthodox interpretation to be realised. Audience: This book will be of interest to graduate level students and researchers whose work involves quantum mechanics, electromagnetic theory, optics and optoelectronics.

Quantum theory as a scientific revolution profoundly influenced human thought about the universe and governed forces of nature. Quantum mechanics is the branch of physics relating to the very small. It results in what may appear to be some very strange conclusions about the physical world. At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at everyday sizes and speeds, cease to be useful. Quantum mechanics (QM) developed over many decades, beginning as a set of controversial mathematical explanations of experiments that the math of classical mechanics could not explain. It began at the turn of the 20th century, around the same time that Albert Einstein published his theory of relativity, a separate mathematical revolution in physics that describes the motion of things at high speeds. Quantum mechanics attempts to describe and account for the properties of molecules and atoms and their constituents--electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons. These properties include the interactions of the particles with one another and with electromagnetic radiation. An essential feature of quantum mechanics is that it is generally impossible, even in principle, to measure a system without disturbing it; the detailed nature of this disturbance and the exact point at which it occurs are obscure and controversial. Theoretical Concepts of Quantum Mechanics represents a rich account of foundation, scientific history of quantum mechanics, relativistic quantum mechanics and field theory, and different methods to solve the Schrodinger equation. This book will be of valuable for students and researchers.

This Växjö conference was devoted to the reconsideration of quantum foundations. Due to increasing research in quantum information theory, especially on quantum computing and cryptography, many questions regarding the foundations of quantum mechanics, which have long been considered to be exclusively of philosophical interest, nowadays play an important role in theoretical and experimental quantum physics.

The first part of this fifth volwne of The Enigmatic Photon consists of three chapters which develop electrodynamics as a gauge field theory with internal 0(3) symmetry using a complex basis ((1), (2), (3)). This is referred to for convenience as 0(3) electrodynamics. The field equations are intrinsically non-linear and non-Abelian, and the classical potential is a physical quantity. The field equations are shown to be self-consistent and a general mathematical basis for the development is given in terms of extended Lie algebra. The third chapter develops radiatively induced fermion resonance (RFR). The opening three chapters are followed by a selection of previously unpublished scientific papers which trace the historical development of 0(3) electrodynamics through the physically observable B(3) field. The editors are greatly indebted to Dr. Laura J. Evans for her painstaking preparation of Part I and Part IT of this volwne. This work included typesetting from original manuscripts and indexing. The production of the five volwnes of this series would not have been possible without her steadfast and generous contributions. Discussions with many colleagues over internet sharpened the ideas behind this volwne. Finally, the organizational support of the Alpha Foundation, founded by Milan Meszaros, proved invaluable during the later preparatory stage~.
