Download or read book The Electron And The Lamb Shift written by Francisco Andre Correa Alegria and published by World Scientific. This book was released on 2024-08-16 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a detailed analytical description of the derivation of the Lamb shift in the Hydrogen atom using quantum field theory. This shift in energy levels, relative to what is predicted in traditional particle physics theory, is due to the phenomena of vacuum fluctuations and vacuum polarization which are accounted for in the quantum field theory as applied in particle physics. The derivation reported is done using perturbation theory and extends up to 4th order. This derivation has been carried out to higher orders by scientists all over the world throughout several decades and agrees exceptionally well with experimental data demonstrating the physical reality of vacuum fluctuations. This book also includes a historical overview of the understanding of the atom and its interaction with electromagnetic radiation as it was in the first half of the 20th century, when the calculation of the Lamb shift was first attempted.
Download or read book 100 Years of Fundamental Theoretical Physics in the Palm of Your Hand written by E. B. Manoukian and published by Springer Nature. This book was released on 2020-10-20 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to integrate, in a pedagogical and technical manner, with detailed derivations, all essential principles of fundamental theoretical physics as developed over the past 100 years. It covers: Quantum physics and Stability Problems in the Quantum World, Minkowski Spacetime Physics Particle Classifications and Underlying Symmetries, Symmetry Violations, Quantum Field Theory of Particle Interactions, Higgs Field Physics, Supersymmetry: A Theory with Mathematical Beauty Superstrings, Gravity and Supergravity, General Relativity Predictions, including Frame Dragging, Intricacies of Black Hole Physics, Perturbative and Non-perturbative Quantum Gravity Intricacies of Modern Cosmology, including Inflation and Power Spectrum If you are in the process of learning, or are lecturing on, any of the subjects above, then this is your book - irrespective of your specialty. With over-specialization and no time to master all the fields given above, students, and perhaps many physicists, may find it difficult to keep up with all the exciting developments going on, and are even less familiar with their underlying technicalities: e.g. they might have heard that the Universe is 13.8 billion years old, but have no idea on how this number is actually computed. This unique book will be of great value to graduate students, instructors and researchers interested in the intricacies and derivations of the many aspects of modern fundamental theoretical physics. And, although a graduate level book, some chapters may also be suitable for advanced undergraduates in their final year.
Download or read book Atoms Molecules and Optical Physics 1 written by Ingolf V. Hertel and published by Springer. This book was released on 2014-10-24 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume of textbooks on atomic, molecular and optical physics, aiming at a comprehensive presentation of this highly productive branch of modern physics as an indispensable basis for many areas in physics and chemistry as well as in state of the art bio- and material-sciences. It primarily addresses advanced students (including PhD students), but in a number of selected subject areas the reader is lead up to the frontiers of present research. Thus even the active scientist is addressed. This volume 1 provides the canonical knowledge in atomic physics together with basics of modern spectroscopy. Starting from the fundamentals of quantum physics, the reader is familiarized in well structured chapters step by step with the most important phenomena, models and measuring techniques. The emphasis is always on the experiment and its interpretation, while the necessary theory is introduced from this perspective in a compact and occasionally somewhat heuristic manner, easy to follow even for beginners.
Download or read book The Enigmatic Electron written by Malcolm H. Mac Gregor and published by Springer Science & Business Media. This book was released on 1992-09-30 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rationale for the Present Book Perhaps the most critical problem facing present-day particle physicistsis to delineate the relationship between classical and quantum systems. This relationship has many facets. Particle-waveduality is one. The concept of the point particle is another. And theconcept of particle mass is yet another. The electron, as the lightest of the charged particles, represents a fundamental "ground state",and many of the essential problems in the murky area between the domainsofclassical and quantum physics can be brought into focus by studyingjust this one particle. Thus the present book is centered on questions that arise in connection with the electron, and in particular with its mass, which has remained an unsolved, and indeed almost unexplored, mystery. Each student ofphysics, beginner and professional alike, has to fashion for himselfa way of thinking about the electron. If, after reading this book, the reader views this topic somewhat differently than before, the efforts of the author will have been amply rewarded. When physicists were confronted with the properties of the electron, they made a conceptualleap into the unknown: they concluded that the electron does not obey classical laws with respect to mechanics (as connected to the spin of the electron), and also with respect to electrodynamics (as connected to the magnetic moment of the electron).

Some 40 chapters cover a broad range of topics in physics written in an engaging and personal style. While the technical level is high, these are not review articles, but rather perspectives on discoveries written by those scientists most closely associated with the original work, as well as future directions of research.
Download or read book Variational Principles in Physics written by Jean-Louis Basdevant and published by Springer Science & Business Media. This book was released on 2007-03-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variational principles have proven to be surprisingly fertile. For example, Fermat used variational methods to demonstrate that light follows the fastest route from one point to another, an idea which came to be a cornerstone of geometrical optics. This book explains variational principles and charts their use throughout modern physics. It examines the analytical mechanics of Lagrange and Hamilton, the basic tools of any physicist. The book also offers simple but rich first impressions of Einstein’s General Relativity, Feynman’s Quantum Mechanics, and more that reveal amazing interconnections between various fields of physics.
Download or read book Redefining the Electron written by Dilip D James and published by Dilip D James. This book was released on 2024-09-01 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the complex landscape of modern physics, the electron has often been shrouded in a veil of esoteric theories and paradoxical concepts. From wave-particle duality to quantum fields, the scientific community has journeyed through a labyrinth of abstract ideas to grasp the essence of this fundamental particle. ‘Redefining the Electron’ seeks to illuminate a path out of this maze by revisiting and reinterpreting fundamental concepts that govern the behaviour of electrons. Through clear and accessible language, the book dismantles the complexities of quantum mechanics and the standard model, emphasizing that not all phenomena require arcane explanations. By revisiting foundational principles, ‘Redefining the Electron’ endeavours to make sense of the electron’s behaviour in terms that resonate with both seasoned scientists and curious minds. In this book, gravity is reimagined as an emergent property of matter, influenced by the density and alignment of virtual photon lines. This approach not only provides a fresh perspective on gravitational forces but also ties together the phenomena of light propagation and gravitational attraction within a unified framework. In a world where complexity often reigns supreme, ‘Redefining the Electron’ champions a return to fundamental principles. By peeling back the layers of modern physics, it reveals a more elegant and comprehensible picture of the electron, offering a renewed sense of clarity and purpose to the study of physics. This book is a must-read for anyone interested in the frontiers of science and the quest to unravel the mysteries of the universe. It serves as a reminder that sometimes, the most profound insights are found not in the complexities of theory but in the simplicity of fundamental truths.

Available in PDF, EPUB and Kindle. Book excerpt: The need for a second edition of our text on Quantum Electrodynamics has given us the opportunity to implement some corrections and amendments. We have corrected a number of misprints and minor errors and have supplied additional explanatory remarks at various places. Furthermore some new material has been included on the magnetic moment of the muon (in Example 5. 6) and on the Lamb shift (in Example 5. 8). Finally, we have added the new Example 3. 17 which explains the equivalent photon method. We thank several colleagues for helpful comments and also are grateful to Dr. R. Mattiello who has supervised the preparation of the second edition of the book. Furthermore we acknowledge the agreeable collaboration with Dr. H. J. K6lsch and his team at Springer-Verlag, Heidelberg. Frankfurt am Main, Walter Greiner July 1994 Joachim Reinhardt Preface to the First Edition Theoretical physics has become a many-faceted science. For the young student it is difficult enough to cope with the overwhelming amount of new scientific material that has to be learned, let alone obtain an overview of the entire field, which ranges from mechanics through electrodynamics, quantum mechanics, field theory, nuclear and heavy-ion science, statistical mechanics, thermodynamics, and solid state theory to elementary-particle physics. And this knowledge should be acquired in just 8-10 semesters, during which, in addition, a Diploma or Master's thesis has to be worked on or examinations prepared for.

(3) Barut contributes a comprehensive review of his own ambitious program in electron theory and quantum electrodynamics. Barut's work is rich with ingenious ideas, and the interest it provokes among other theorists can be seen in the cri tique by Grandy. Cooperstock takes a much different approach to nonlinear field-electron coupling which leads him to conclusions about the size of the electron. (4) Capri and Bandrauk work within the standard framework of quantum electrodynamics. Bandrauk presents a valuable review of his theoretical approach to the striking new photoelectric phenomena in high intensity laser experiments. (5) Jung proposes a theory to merge the ideas of free-free transitions and of scattering chaos, which is becoming increasingly important in the theoretical analysis of nonlinear optical phenomena. For the last half century the properties of electrons have been probed primarily by scattering experiments at ever higher energies. Recently, however, two powerful new experimental techniques have emerged capable of giving alternative experimental views of the electron. We refer to (1) the confinement of single electrons for long term study, and (2) the interaction of electrons with high intensity laser fields. Articles by outstanding practitioners of both techniques are included in Part II of these Proceedings. The precision experiments on trapped electrons by the Washington group quoted above have already led to a Nobel prize for the most accurate measurements of the electron magnetic moment.
Download or read book Advanced Quantum Mechanics written by Freeman J. Dyson and published by World Scientific. This book was released on 2011 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renowned physicist and mathematician Freeman Dyson is famous for his work in quantum mechanics, nuclear weapons policy and bold visions for the future of humanity. In the 1940s, he was responsible for demonstrating the equivalence of the two formulations of quantum electrodynamics OCo Richard Feynman''s diagrammatic path integral formulation and the variational methods developed by Julian Schwinger and Sin-Itiro Tomonoga OCo showing the mathematical consistency of QED. This invaluable volume comprises the legendary lectures on quantum electrodynamics first given by Dyson at Cornell University in 1951. The late theorist Edwin Thompson Jaynes once remarked, OC For a generation of physicists they were the happy medium: clearer and better motivated than Feynman, and getting to the point faster than SchwingerOCO. This edition has been printed on the 60th anniversary of the Cornell lectures, and includes a foreword by science historian David Kaiser, as well as notes from Dyson''s lectures at the Les Houches Summer School of Theoretical Physics in 1954. The Les Houches lectures, described as a supplement to the original Cornell notes, provide a more detailed look at field theory, a careful and rigorous derivation of Fermi''s Golden Rule, and a masterful treatment of renormalization and Ward''s Identity. Future generations of physicists are bound to read these lectures with pleasure, benefiting from the lucid style that is so characteristic of Dyson''s exposition.

Download or read book Quantum Mechanics of One and Two Electron Atoms written by Hans A. Bethe and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all of this book is taken from an article prepared for a volume of the Encyclopedia of Physics. This article, in turn, is partly based on Dr. Norbert Rosenzweig's translation of an older article on the same subject, written by one of us (H.A.B.) about 25 years ago for the Geiger-Scheel Handbuch der Physik. To the article written last year we have added some Addenda and Errata. These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes. The aim of this book is two-fold. First, to act as a reference work on calcu lations pertaining to hydrogen-like and helium-like atoms and their comparison with experiments. However, these calculations involve a vast array of approximation methods, mathematical tricks and physical pictures, which are also useful in the application of quantum mechanics to other fields. In many sections we have given more general discussions of the methods and physical ideas than is necessary for the study of the H- and He-atom alone. We hope that this book will thus at least partly fulfill its second aim, namely to be of some use to graduate students who wish to learn "applied quantum mechanics". A basic knowledge of the principles of quantum mechanics, such as given in the early chapters of Schiff's or Bohm's book, is presupposed.
Download or read book Atomic Physics with Heavy Ions written by Heinrich F. Beyer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to one of the most active domains of atomic physic- atomic physics of heavy positive ions. During the last 30 years, this terrain has attracted enormous attention from both experimentalists and theoreti cians. On the one hand, this interest is stimulated by rapid progress in the development of laboratory ion sources, storage rings, ion traps and methods for ion cooling. In many laboratories, a considerable number of complex and accurate experiments have been initiated, challenging new frontiers. Highly charged ions are used for investigations related to fundamental research and to more applied fields such as controlled nuclear fusion driven by heavy ions and its diagnostics, ion-surface interaction, physics of hollow atoms, x-ray lasers, x-ray spectroscopy, spectrometry of ions in storage rings and ion traps, biology, and medical therapy. On the other hand, the new technologies have stimulated elaborate theo retical investigations, especially in developing QED theory, relativistic many body techniques, plasma-kinetic modeling based on the Coulomb interactions of highly charged ions with photons and various atomic particles - electrons, atoms, molecules and ions. The idea of assembling this book matured while the editors were writ ing another book, X-Ray Radiation of Highly Charged Ions by H. F. Beyer, H. -J. Kluge and V. P. Shevelko (Springer, Berlin, Heidelberg 1997) covering a broad range of x-ray and other radiative phenomena central to atomic physics with heavy ions.
