Atomic frequency standards are very stable and accurate frequency sources. They are now used, for example, in high-speed communication, in navigation systems and in time-keeping. This study, which examines present knowledge regarding the operation of such devices, is designed to be used by the newcomer to the field as well as by the experienced researcher.

Atomic frequency standards provide the most accurate measurements in physics. The Quantum Physics of Atomic Frequency Standards is an extensive survey of the subject covering both theoretical and experimental aspects together with applications. As an accessible and essential reference it will be invaluable to experienced researchers and beginners alike. The first volume begins with a quantum mechanics treatment of the interaction of static fields and electromagnetic radiation with atoms and molecules. Each of the important phenomena - noise, relaxation, broadening and frequency shifts - is treated in detail and optical pumping and population inversion are explained. With all the background material now in place the major part of these volumes is devoted to a theoretical analysis of the operation of the numerous atomic frequency standards that are either in use, are being studied or have been proposed. * Caesium atomic beam frequency standards * Hydrogen maser * Rubidium frequency standards * Mercury ion trap * Frequency stabilized lasers In the final chapter the authors discuss the impact of atomic frequency standards on navigation and communication systems, in industry, in new technology and on fundamental research.

The Quantum Physics of Atomic Frequency Standards: Recent Developments, Second Edition, covers advances in atomic frequency standards (atomic clocks) from the last several decades. It explains the use of various techniques, such as laser optical pumping, coherent population trapping, laser cooling, and electromagnetic and optical trapping, in the implementation of classical microwave and optical atomic frequency standards. It provides an up-to-date, in-depth view of the vast improvements to atomic clocks that have occurred in the last 25 years. The improved stability and accuracy enable the verification of physical concepts used in fundamental theories, such as relativity, as well as the stability of fundamental constants intrinsic to those theories. The book first discusses improvements to conventional atomic frequency standards, highlighting the main limitations of those frequency standards and the physical basis of the limitations. It then describes how advances in the theory and applications of atomic physics have opened new avenues in frequency standards. The authors go on to explore the research and development of new microwave and optical frequency standards before presenting the results in frequency stability and accuracy achieved with these new frequency standards. They also illustrate the application of atomic clocks in metrology, telecommunications, navigation, and other areas and give some insight into future work. This new edition examines updated developments on the frequency standards, alongside content on the International System of Units (SI) and the role of atomic clocks on their base units. It also features new material on Coherent Population Trapping and new developments in the field of optical frequency standards. Key Features: Describes the basic physics, including quantum mechanics, behind the operation of atomic clocks. Explores new frequency standards that provide better stability and accuracy than older, more conventional standards. Discusses the importance of the field in the general context of physics. Jacques Vanier is retired from the National Research Council of Canada and as adjunct professor in the Physics Department at the University of Montreal. He is a fellow of the Royal Society of Canada, the American Physical Society, and the Institute of Electrical and Electronic Engineers. He has written more than 120 journal articles and proceedings papers and is the author of several books on masers, lasers, and atomic clocks. His main research work is oriented toward the understanding and application of quantum electronics phenomena. Cipriana Tomescu is retired from The Institute of Physics, Bucharest, Romania, and as invited researcher in the Physics Department at the University of Montreal. She is the author of numerous articles in scientific journals and conference proceedings. Her research involves state-of-the-art atomic frequency standards and H masers.

Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Carl Wieman's contributions have had a major impact on defining the field of atomic physics as it exists today. His ground-breaking research has included precision laser spectroscopy; using lasers and atoms to provide important table-top tests of theories of elementary particle physics; the development of techniques to cool and trap atoms using laser light, particularly in inventing much simpler, less expensive ways to do this; the understanding of how atoms interact with one another and light at ultracold temperatures; and the creation of the first Bose-Einstein condensation in a dilute gas, and the study of the properties of this condensate. In recent years, he has also turned his attention to physics education and new methods and research in that area. This indispensable volume presents his collected papers, with annotations from the author, tracing his fascinating research path and providing valuable insight about the significance of the works.
