If you found any error, please submit an Numerous worked examples and end-of-chapter problems enable students to reproduce classic results and to master quantum field theory as it is used today. How does QFT relate to other areas of physics, like condensed matter physics or cosmology? QFT finds applications across numerous fields, including condensed matter physics (describing collective behavior of electrons in solids), cosmology (explaining the early universe), and quantum computing. He has rethought the whole presentation of the subject, from the introductory and foundational concepts to new developments such as effective field theory descriptions of quark dynamics.
