Customer Reviews of Introduction to Quantum Field Theory
Excellent informal QFT intro You want to know what is Casimir effect, renormalization and Callan-Symanzic Eqn, effective action and path integral. You take a standard QFT course (say, Weinberg or Peskin) and find yourself overwhelmed with peculiarities of Dirac spinors and Lorentz group representations. You feel you are not going anywhere: you are not learning QFT, really! Maybe you are even not a particle physicist after all. Then this book is for YOU! Authors do a great job explaining the essence of QFT (as an interacting theory with an infinite number degrees of freedom) using the scalar field Lagrangian with the quartic interaction as a prime example. It is amazing how far one actually can go with such a model! Each chapter contains an illustrative calculation of a physical quantity (say, the Casimir energy, Ch. 5), with all the details, and without unnecessary complications. One also learns a great deal of the path integral techniques (e.g. instantons), which is extremely important in a variety of fields (QCD, condensed matter, statistical physics, etc). Overall, a highly recommended reading.
A great introductory course
I've looked at many books on quantum field theory and this is without doubt the best introductory work I have found. The Weinberg book jumps in at the deep end, the Kaku book jumps in at about 6 feet deep but this one allows you to at least climb into the pool. It's a rare intelligence to be aware of how to lead one's reader along the learning curve and these authors display it. Typo errors occur at the rate of about one every two pages (did anyone read the proofs?) but they are easily discovered if one follows the math carefully.
