媒体评论 “There is a need for a book on Quantum Field Theory that is not directed at specialists but, rather, sets out the concepts underlying this subject for a broader scientific audience and conveys joy in their beauty. Lancaster and Blundell have written with this goal in mind, and they have succeeded admirably.” ——Michael Peskin, SLAC National Accelerator Laboratory, Stanford University “This wonderful and exciting book is optimal for physics graduate students. ... The physical explanations are exceedingly well written and integrated with mathematics. Quantum field theory is the next big thing and this book will help the reader to understand and use the theory.” ——Optics & Photonics News
