Quantum Field Theory: A Modern Introduction is undoubtedly the standard setting textbook in this field; as it is the only up-to-date introductory textbook to cover the `modern' approach to quantum field theory (QFT).In this textbook, Michio Kaku, goes far beyond existing texts, and presents material vital to the modern approach to QFT. Topics such as critical phenomena, lattice gauge theory, supersymmetry, quantum gravity, supergravity, and superstrings are all included in this textbook and are not included in other textbooks on QFT.There are also over 260 exercises included within the text.
