Quantum Field Theory (QFT) is the theoretical framework that combines classical field theory, special relativity, and quantum mechanics. It has become the basis of particle physics and condensed matter research. QFT provides a language for understanding the fundamental particles and forces of nature, describing how fields permeate space-time and how their excitations correspond to particles.
Horatiu Nastase, a researcher in theoretical physics, structures his approach to Quantum Field Theory (QFT) by balancing foundational mechanics with high-level applications like string theory and supersymmetry. Unlike traditional texts that isolate perturbative methods from non-perturbative phenomena, this book integrates them early on.
Published by Cambridge University Press in late 2019, Nastase's Introduction to Quantum Field Theory is designed as a rigorous, two-semester graduate course. What immediately distinguishes this textbook is its balanced approach: it gives equal emphasis to the and the Feynman path integral formalism , ensuring students develop a well-rounded mastery of the subject’s foundational techniques.
