Master Quantum Field Theory and Renormalization group with Path Integrals: Intuitive Insights & Practical Applications

Authors: Rejzner, Kasia
A brief, though complete and self-consistent, introduction to perturbative Algebraic Quantum Field Theory (pAQFT)
Written by one of the leading experts in the field
The reader get all the prerequisites to understand QFT concepts used in cutting edge research in particle physics, cosmology and solid state physics.
A useful reference for mathematicians interested in QFT

by Peter W. Milonni (Author)
This is an introduction to the quantum theory of light and its broad implications and applications. A significant part of the book covers material with direct relevance to current basic and applied research, such as quantum fluctuations and their role in laser physics and the theory of forces between macroscopic bodies (Casimir effects)

by Victor Ilisie (Author)
Essential complementary tool for beginners in Quantum Fields Theory
Demystifies renormalization
Provides a reader-friendly introduction to tensor calculus
Analyzes infrared and ultraviolet poles

This textbook is intended to be used in an introductory course in quantum field theory. It assumes the standard undergraduate education of a physics major and it is designed to appeal to a wide array of physics graduate students, from those studying theoretical and experimental high energy physics to those interested in condensed matter, optical, atomic, nuclear and astrophysicists. It includes a thorough development of the field theoretic approach to nonrelativistic many-body physics as a step in developing a broad-based working knowledge of some of the basic aspects of quantum field theory. It presents a logical, step by step systematic development of relativistic field theory and of functional techniques and their applications to perturbation theory with Feynman diagrams, renormalization, and basic computations in quantum electrodynamics.
