Quantum Field Theory [Paperback]

L. H. Ryder (Author)

Book Description

Publication Date: October 31, 1986 | ISBN-10: 052133859X | ISBN-13: 978-0521338592

This book describes, as simply as is possible, the ideas and techniques of quantum field theory, on which is based our current understanding of subnuclear physics. In recent years this has advanced considerably with the discovery of charmed particles and the weak intermediate vector bosons predicted by gauge theories. After a brief survey of particle physics, the quantum theory of scalar and spinor fields, and then of gauge fields, is developed. The emphasis throughout is on functional methods, which have Played a large part in modern field theory. The book concludes with a brief survey of 'topological' objects in field theory. The author assumes a knowledge of quantum mechanics and special relativity.

Editorial Reviews

Review

'Without reservations, I give my strongest recommendation to every beginning student of physics to acquire and read Quantum Field Theory by L. H. Ryder.' D. V. Ahluwalia, Foundations of Physics

Book Description

After a brief overview of particle physics and a survey of relativistic wave equations and Lagrangian methods, this text develops the quantum theory of scalar and spinor fields, and then of gauge fields. The emphasis throughout is on functional methods, which have played a large part in modern field theory. --This text refers to an out of print or unavailable edition of this title.

5.0 out of 5 stars An Inspiring Introduction to QFT, September 30, 2002

By 

Derek Lee (St. Paul, MN USA) - See all my reviews

This review is from: Quantum Field Theory (Paperback)

One of the basic questions in the education of theoretical physics is, what is a good way of introducing QFT and giving the student a taste of what is to come? In my opinion, this book offers a fine solution to this thorny problem.
There are many sides to this question; for example, there is the view that the students should be exposed to this vast topic in a complete and thorough way (for such a text, I HIGHLY recommend Weinberg's 3 volume set, which, if not commonly regarded as a classic yet, soon will be), and also there is the point of view that most of the students studying QFT are experimentalists, so they should first be exposed to how to calculate amplitudes and cross sections for useful processes as soon as possible (see Peskin-Schroder for an outstanding exemplification of this principle). Both of these points of view have strong arguments supporting them, and there are many other reasonable opinions that might be taken; perhaps this is an indication that there is not any one approach to this subject which is a good introduction for all, but rather that the student must choose intelligently which text he/she finds they are most comfortable with. However, I can say that for me at least, this book had just the right selection of topics and at just the right level to get me interested in the subject and to give me a taste as to what it would be like if I were to go into it in more depth (which indeed I did). Other reviewers are quite right in pointing out that there are several inaccuracies in this text; also in more than a few places the treatment is considerably less clear than it might have been (this is one of the main strengths of Weinberg's set; every last detail is crystal clear, and the physical reasoning in the derivations is very rarely muddled in the math). Perhaps in this sense, the book could have been better written, and just by this element of style, I probably would have rated this 4 stars. However, I think that these valid criticisms are more than offset by the overwhelming strength of the book:that it is truly inspiring. Several reviewers have gone over details; I shall not rehash these matters, but instead leave off with the statement that this book was the best introduction to QFT that I could have bought.

5.0 out of 5 stars The most readable QFT textbook available., August 30, 2000

By 

R. Ball (London W14, England United Kingdom) - See all my reviews
(REAL NAME)   

This review is from: Quantum Field Theory (Paperback)

Of all the QFT textbooks I have surveyed, this is by far the most accessable and readable. It has an ideal balance between clear well-written text and carefully paced equations, without the usual "after some manipulation..." or "combining with the previous results and rearranging..." or the fearful "it can be seen that..." which usually conceal chasms in reasoning that require an hour or so's hackwork to establish. It is nicely self-contained, having short digressions to derive some mathematical or topological results without sending the reader to consult other sources for clarification. I still have the first edition for which my only minor quibble would be the rather frequent typo's in the formulae, but at least picking them out kept me alert. These may have been cleaned up in the later edition.

5.0 out of 5 stars Good Introduction, May 13, 2001

By 

David Dreisigmeyer (Fort Collins, CO United States) - See all my reviews

This review is from: Quantum Field Theory (Paperback)

A very readable intro to QFT. After having tried a dozen or so different QFT books, this is the one that I eventually used. A nice feature is its emphasis on the path integral and its use in QFT. This book does not have any problems included. In order to gain some experience actually solving problems the book should be supplemented with another. I would recommend that Schwabl's "Advanced Quantum Mechanics" and Griffiths' "Introduction to Elementary Particles" be used in conjunction with Ryder. They complement the text perfectly. Also, you can't expect to learn QFT from only one source.
