"Quantum Theory of Near-field Electrodynamics" gives a self-contained account of the fundamental theory of field-matter interaction on a subwavelength scale. The quantum physical behavior of matter (atoms and mesoscopic media) in both classical and quantum fields is treated. The role of local-field effects and nonlocal electrodynamics, and the tight links to the theory of spatial photon localization are emphasized. The book may serve as a reference work in the field, and is of general interest for physicists working in quantum optics, mesoscopic electrodynamics and physical optics. The macroscopic and microscopic classical theories form a good starting point for the quantum approach, and these theories are presented in a manner appropriate for graduate students entering near-field optics.

The borderline of quantum electrodynamics and quantum optics offer spectacular results and problems concerning the foundations of radiation theory. Perhaps the major new viewpoint that has emerged from recent investigations is that one can now work inside a time-dependent quantum process, whereas up to now all elementary quantum processes were either stationary, or one worked with asymptotic in-and out-states, i.e. an S-matrix approach. In the-rirst part of this volume, the Quantum Electrodynamics, the present status of the main approaches to this most accurate of all physical theories are discussed: the Hamiltonian approach, the Green's function approach with particular emphasis to bound state problems, and the newer, nonperturbative approach. The latest numerical results on radiative corrections, Lamb shifts and anomalous magnetic moments are reviewed with new results for high Z atoms. Also discussed are different theoretical interpretations of the radiative phenomena as due to quantized field vacuum fluctuations or due to self energy. A small group of contributions are devoted to the physics and mathematical description of decaying or unstable states in quantum theory. This remarkable phenomenon of quantum theory still needs complete clarification, it is a time-dependent phenomenon, which can be described also by asymptotic S-matrix methods, but with complex energies.

This book resolves fundamental questions of quantum theory and offers arguably the strongest evidence yet in support of string theory. It is essential reading for everyone in physics, physical mathematics, and the philosophy of science. The authors model electrons as an ensemble of strings subject to the laws of classical statistical mechanics. This model shows the Schrodinger equation to be the low speed descriptor of equilibrium and near-equilibrium states but not of quantum jumps. Like other statistical systems, the electron ensemble passes through all possible intrinsic states. As a high energy eigenstate electron ensemble passes through an appropriate structure, it regeneratively produces an encompassing standing energy field. Regenerative field buildup enables the electron to be a radiative band pass filter: it is an efficient radiator at the buildup frequency and phase, but all other frequencies and phases are blocked. When a matching external field trigger is applied depending upon therelative phasings, the standing energy is either absorbed or emitted with full directivity.

In this book the author carefully analyses the role of the concept of causality in Quantum Electrodynamics. This approach makes it possible for the first time to publish a textbook on QED which not only includes full proofs and detailed calculations but is also mathematically rigorous. The book begins with Dirac's theory in part one, followed in part two by the quantum theory of free fields including a new approach to the concept of exterior fields. The third part is devoted to the study of the S-matrix of QED avoiding ultraviolet divergence. The most important physical results of QED are derived, and significant themes such as unitarity and renormalizability of the theory are discussed. This slim book addresses graduate students in physics. From the reviews: "In the summary on the back cover the unheard-of statement appears that now the first (mathematically) rigorous textbook on Quantum Electrodynamics was on hand. ... In fact, "Finite Quantum Electrodynamics" does justice to this claim. And, in addition, in a pregnant, lifely form. On 220 pages G. Scharf (Zurich) succeeds in presenting a concise description of QED ... As promised, only finite quantities appear ... In Russia I often feel frustrated that I studied Latin in school and Russian was not offered. Now I have the same feeling after reading Scharf's book. I studied the wrong grammar up to now." #Translated from a review by Thomas Schücker in Physik in unserer Zeit#1

Kallen's Quantenelektrodynamik provides a concise treatment of the subject. Its strong points are the careful attention to ex planatory detail, the methodical coverage of all the maj or results and the straightforward, lucid style. Certainly it will be a val uable reference for one learning the subject or for one who re quires the details of the practical results. Of course modern quantum field theory has now grown far beyond its dramatic be ginnings in electrodynamics and we have therefore included some references to introduce the reader to the more recent and more specialized literature. We have corrected some minor errors: we would appreciate it if readers would inform us of any others which they find. We thank Professors Paul Urban and C. MtSller for permission to use the biographical material on Kallen. We also wish to thank Springer-Verlag for undertaking publication of this edition by an unorthodox method, but one which will reduce the cost to the reader. In particular, we are grateful to Dr. H. Mayer-Kaupp and Mr. Herb Stillman for their kind cooperation. Finally, we thank Mr. Michael Teague for reading and commenting on the first dozen sections and we thank Mrs. Joanne Downs for ed iting and typing the final manuscript. May 1972 C. K. Iddings M.
