Book Synopsis The Development of the Action Principle by : Walter Dittrich
Download or read book The Development of the Action Principle written by Walter Dittrich and published by Springer Nature. This book was released on 2021-05-29 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the historical development of the principle of stationary action from the 17th to the 20th centuries. Reference is made to the most important contributors to this topic, in particular Bernoullis, Leibniz, Euler, Lagrange and Laplace. The leading theme is how the action principle is applied to problems in classical physics such as hydrodynamics, electrodynamics and gravity, extending also to the modern formulation of quantum mechanics and quantum field theory, especially quantum electrodynamics. A critical analysis of operator versus c-number field theory is given. The book contains many worked examples. In particular, the term "vacuum" is scrutinized.The book is aimed primarily at actively working researchers, graduate students and historians interested in the philosophical interpretation and evolution of physics; in particular, in understanding the action principle and its application to a wide range of natural phenomena.

Book Synopsis The Schwinger Action Principle and Effective Action by : David J. Toms
Download or read book The Schwinger Action Principle and Effective Action written by David J. Toms and published by Cambridge University Press. This book was released on 2012-08-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the Schwinger action principle in quantum mechanics and quantum field theory, with applications to a variety of different models including Bose-Einstein condensation, the Casimir effect, and trapped Fermi gases. The book begins with a brief review of the action principle in classical mechanics and classical field theory. It then moves on to quantum field theory, focusing on the effective action method. This is introduced as simply as possible by using the zero-point energy of the simple harmonic oscillator as the starting point. The book concludes with a more complete definition of the effective action, and demonstrates how the provisional definition used earlier is the first term in the systematic loop expansion. The renormalization of interacting scalar field theory is presented to two-loop order. This book will interest graduate students and researchers in theoretical physics who are familiar with quantum mechanics.

Book Synopsis A Birman-Schwinger Principle in Galactic Dynamics by : Markus Kunze
Download or read book A Birman-Schwinger Principle in Galactic Dynamics written by Markus Kunze and published by Springer Nature. This book was released on 2021-08-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph develops an innovative approach that utilizes the Birman-Schwinger principle from quantum mechanics to investigate stability properties of steady state solutions in galactic dynamics. The opening chapters lay the framework for the main result through detailed treatments of nonrelativistic galactic dynamics and the Vlasov-Poisson system, the Antonov stability estimate, and the period function $T_1$. Then, as the main application, the Birman-Schwinger type principle is used to characterize in which cases the “best constant” in the Antonov stability estimate is attained. The final two chapters consider the relation to the Guo-Lin operator and invariance properties for the Vlasov-Poisson system, respectively. Several appendices are also included that cover necessary background material, such as spherically symmetric models, action-angle variables, relevant function spaces and operators, and some aspects of Kato-Rellich perturbation theory. A Birman-Schwinger Principle in Galactic Dynamics will be of interest to researchers in galactic dynamics, kinetic theory, and various aspects of quantum mechanics, as well as those in related areas of mathematical physics and applied mathematics.

Book Synopsis Classical Electrodynamics by : Julian Schwinger
Download or read book Classical Electrodynamics written by Julian Schwinger and published by CRC Press. This book was released on 2019-05-20 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical Electrodynamics captures Schwinger's inimitable lecturing style, in which everything flows inexorably from what has gone before. Novel elements of the approach include the immediate inference of Maxwell's equations from Coulomb's law and (Galilean) relativity, the use of action and stationary principles, the central role of Green's functions both in statics and dynamics, and, throughout, the integration of mathematics and physics. Thus, physical problems in electrostatics are used to develop the properties of Bessel functions and spherical harmonics. The latter portion of the book is devoted to radiation, with rather complete treatments of synchrotron radiation and diffraction, and the formulation of the mode decomposition for waveguides and scattering. Consequently, the book provides the student with a thorough grounding in electrodynamics in particular, and in classical field theory in general, subjects with enormous practical applications, and which are essential prerequisites for the study of quantum field theory.An essential resource for both physicists and their students, the book includes a ?Reader's Guide,? which describes the major themes in each chapter, suggests a possible path through the book, and identifies topics for inclusion in, and exclusion from, a given course, depending on the instructor's preference. Carefully constructed problems complement the material of the text, and introduce new topics. The book should be of great value to all physicists, from first-year graduate students to senior researchers, and to all those interested in electrodynamics, field theory, and mathematical physics.The text for the graduate classical electrodynamics course was left unfinished upon Julian Schwinger's death in 1994, but was completed by his coauthors, who have brilliantly recreated the excitement of Schwinger's novel approach.
Book Synopsis An Introduction To Quantum Field Theory by : Michael E. Peskin
Download or read book An Introduction To Quantum Field Theory written by Michael E. Peskin and published by CRC Press. This book was released on 2018-05-04 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
Book Synopsis Topics in Quantum Field Theory by : T. W. B. Kibble
Download or read book Topics in Quantum Field Theory written by T. W. B. Kibble and published by . This book was released on 1958 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject matter of this thesis falls into two distinct parts. Chapters II to IV are devoted to a discussion of Schwinger's action principle, and chapters V and VI are concerned with the proof of dispersion relations for inelastic meson-nucleon scattering. The material of chapter II is based on some work done in collaboration with Dr. J.C. Polkinghorne, which has been published (Kibble and Polkinghorne 1957). This work was concerned with the clarification of certain points connected with the class of permissible variations in Schwinger's principle. There are, however, substantial changes in the present treatment, principally deriving from the introduction, in section II-5, of the concept of relative phases. This chapter is restricted to the case of non-relativistic quantum theory, and the discussion is extended to relativistic quantum field theory in chapter III. These chapters are devoted to a reformulation of Schwinger's action principle, and an investigation of the consequences of the new form of the action principle. Some of this material is necessarily contained in the work of Schwinger (1951, 1953a), but the treatment differs from his in several important respects. These are discussed in greater detail in section 2. Chapter IV is devoted to a discussion of higher order spinor Lagrangians, with particular reference to the use of a two-component field satisfying a second-order equation rather than a four-component spinor satisfying a first-order equation. This procedure has been suggested by Feynman and Gell-Mann (1958) in connection with their universal Fermi interaction. The work presented in this chapter was done jointly with Dr. J.C. Polkinghorne, and has been published (Kibble and Polkinghorne 1958). Chapters V and VI are devoted to a proof of the dispersion relations for the process in which a single meson is scattered on a nucleon into a state with several mesons. The proof follows the general lines of that by Bogolyubov, Medvedev and Polivanov (1956) for the case of elastic meson-nucleon scattering, This work has also been published (Kibble 1958). The notation employed in the thesis is summarized in appendix A. Appendix B is devoted to a discussion of consistency conditions on the Lagrangian function. The chapter number is omitted in references to sections or equations, except in the case of cross references between chapters.
