Lectures on QED and QCD

Author: A. G. Grozin
Publisher: World Scientific
ISBN: 9789812569141
Release Date: 2007
Genre: Science

The increasing precision of experimental data in many areas of elementary particle physics requires an equally precise theoretical description. In particular, radiative corrections (described by one- and multi-loop Feynman diagrams) have to be considered. Although a growing number of physicists are involved in such projects, multi-loop calculation methods can only be studied from original publications. With its coverage of multi-loop calculations, this book serves as an excellent supplement to the standard textbooks on quantum field theory. Based around postgraduate-level lectures given by the author, the material is suitable for both beginners and graduate students.

QED and the Men who Made it

Author: Silvan S. Schweber
Publisher: Princeton University Press
ISBN: 0691033277
Release Date: 1994
Genre: Science

"In the 1930s, physics was in a crisis. There appeared to be no way to reconcile the new theory of quantum mechanics with Einstein's theory of relativity. In the post-World War II period, four eminent physicists rose to the challenge and developed a calculable version of quantum electrodynamics (QED). This formulation of QED was pioneered by Freeman Dyson, Richard Feynman, Julian Schwinger, and Sin-Itiro Tomonaga, three of whom won the Nobel Prize for their work. Schweber begins with an account of the early work done by physicists such as Dirac and Jordan, and describes the gathering of eminent theorists at Shelter Island in 1947. The rest of his narrative comprises individual biographies of the four physicists, discussions of their major contributions, and the story of the scientific community in which they worked"--Publisher's description.

QED Coherence in Matter

Author: Giuliano Preparata
Publisher: World Scientific
ISBN: 9810222491
Release Date: 1995
Genre: Science

Up until now the dominant view of condensed matter physics has been that of an ?electrostatic MECCANO? (erector set, for Americans). This book is the first systematic attempt to consider the full quantum-electrodynamical interaction (QED), thus greatly enriching the possible dynamical mechanisms that operate in the construction of the wonderful variety of condensed matter systems, including life itself.A new paradigm is emerging, replacing the ?electrostatic MECCANO? with an ?electrodynamic NETWORK,? which builds condensed matter through the long range (as opposed to the ?short range? nature of the usual electrostatic forces) electrodynamical interaction; this interaction creates ?coherent configurations? of the elementary systems (atoms and molecules), which oscillate in phase with a coherent macroscopic (and classical) electromagnetic field that, through the strong interaction with matter, remains trapped inside it.

QED

Genre: Science

Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely, quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's introduction places Feynman’s book and his seminal contribution to QED in historical context and further highlights Feynman’s uniquely appealing and illuminating style.

Non Relativistic QED Theory of the van der Waals Dispersion Interaction

Author: Akbar Salam
Publisher: Springer
ISBN: 9783319456065
Release Date: 2016-09-29
Genre: Science

This book provides details of the calculation of the interaction between two neutral polarizable atoms or molecules using molecular quantum electrodynamics (QED). To better understand the origin of this force, it briefly outlines molecular QED theory, the well-known van der Waals dispersion potential first evaluated by Casimir and Polder, who accounted for retardation effects. It presents different calculation schemes for the evaluation of the dispersion potential and also discusses energy shifts involving electric quadrupole and octupole moments, along with discriminatory dispersion potentials. Further, it explores in detail non-additive dispersion interaction energies between three-bodies, as well as the effects of higher multipole moment correction terms, and provides results for specific geometries such as collinear and equilateral triangles. Lastly, it computes near and far-zone asymptotic limits for both pair and many-body potentials, with the former shown to agree with less rigorous semi-classical calculations.

Quantum Electrodynamics

Author: Toichiro Kinoshita
Publisher: World Scientific
ISBN: 9810202148
Release Date: 1990
Genre: Science

Quantum electrodynamics is an essential building block and an integral part of the gauge theory of unified electromagnetic, weak, and strong interactions, the so-called standard model. Its failure or breakdown at some level would have a most profound impact on the theoretical foundations of elementary particle physics as a whole. Thus the validity of QED has been the subject of intense experimental tests over more than 40 years of its history. This volume presents an up-to-date review of high precision experimental tests of QED together with comprehensive discussion of required theoretical work.

Q E D

Author: Richard Phillips Feynman
Publisher: Penguin Books
ISBN: 0140125051
Release Date: 1990
Genre: Electrons

Quantum electrodynamics - or QED, for short - is the revolutionary theory that explains how light and electrons interact. Thanks to Richard Feynman and his colleagues, who won the Nobel Prize for their ground-breaking work in this area, it is also one of the rare parts of physics that is known for sure, a theory that has stood the test of time. In these entertaining and witty lectures Feynman uses everyday examples to explain the deepest and most complex mysteries of the world around us, in the definitive introduction to QED.

Genre: Computers

Since the need for a third edition of this book has arisen, we have endeavoured to improve and extend it in several ways. At many places small changes were made, misprints have been corrected, and references have been added. In Chap. 5 new theoretical and experimental results on the Lamb shift in heavy atoms and on the anomalous magnetic moment of the muon are reported. We have also added a number of new topics in Chaps. 3, 5, and 7 in the form of examples and exercises. Example 3. 19 contains a detailed treatment of electron-positron pair production in the collision of a high-energy photon with a laser beam. This is supplemented by Exercise 3. 20 where a closed solution of the Dirac equation in the field of a plane wave is derived. Furthermore, Example 5. 4 on the running coupling constant in QED and Example 7. 6 on the supercritial point charge prob lem have been added. Finally, Example 7. 8 treats the birefringence of the QED vacuum in a strong magnetic field. We thank all colleagues and readers who have informed us about misprints in the book and are grateful to the team at Springer-Verlag for expertly handling the preparation of this new edition. Frankfurt am Main, Walter Greiner August 2002 Joachim Reinhardt Preface to the Second Edition The need for a second edition of our text on Quantum Electrodynamics has given us the opportunity to implement some corrections and amendments.

Genre: Literary Collections

The great world disaster, ushered in with the dawn of that August morning in 1914, has already brought revolutionary changes in many departments of our thinking. But not the least of the surprises awaiting an amazed world, whenever attention can again be directed to such subjects, will be the realization that we have now definitely outgrown many notions in science and philosophy which in the old order of things were supposed to have been eternally settled. There are but two theories regarding the origin of our world and of the various forms of plants and animals upon it, Creation and Evolution, --the latter assuming many modifications. The essential idea of the Evolution theory is _uniformity_; that is, it seeks to show that life in all its various forms and manifestations probably originated by causes similar to or identical with forces and processes now prevailing. It teaches the absolute supremacy and the past continuity of natural law as now observed. It says that the changes now going on in our modern world have always been in action and that these present-day natural changes and processes are as much a part of the origin of things as anything that ever took place in the past. In short, Evolution as a philosophy of nature is an effort to smooth out all distinction between Creation and the ordinary processes of nature that are now under the regime of "natural law."
