Quantum Field Theory - Padmanabhan Thanu
This book describes, in clear terms, the Why, What and the How of Quantum Field Theory. Non-perturbative aspects and the Wilsonian interpretation of field theory are emphasized right from the start. The raison d'etre of QFT is explained by starting from the dynamics of a relativistic particle and demonstrating how it leads to the notion of quantum fields.
Complementing the conceptual aspects, the book also develops all the relevant mathematical techniques in detail, leading e.g., to the computation of anomalous magnetic moment of the electron and the two-loop renormalisation of the self-interacting scalar field. Several interesting topics such as the Schwinger effect, Davies-Unruh effect, Casimir effect and spontaneous symmetry breaking introduce the reader to the elegance and breadth of applicability of field theoretical concepts. It contains nearly a hundred problems, of varying
