Quantum Field Theory

<p><b>The only</b><b> graduate-level textbook on quantum field theory that fully integrates perspectives from high-energy condensed-matter and statistical physics</b> <p/>Quantum field theory was originally developed to describe quantum electrodynamics and other fundamental problems in high-energy physics but today has become an invaluable conceptual and mathematical framework for addressing problems across physics including in condensed-matter and statistical physics. With this expansion of applications has come a new and deeper understanding of quantum field theory--yet this perspective is still rarely reflected in teaching and textbooks on the subject. Developed from a year-long graduate course Eduardo Fradkin has taught for years to students of high-energy condensed-matter and statistical physics this comprehensive textbook provides a fully multicultural approach to quantum field theory covering the full breadth of its applications in one volume.</p><ul><li>Brings together perspectives from high-energy condensed-matter and statistical physics in both the main text and exercises</li><li>Takes students from basic techniques to the frontiers of physics</li><li>Pays special attention to the relation between measurements and propagators and the computation of cross sections and response functions</li><li>Focuses on renormalization and the renormalization group with an emphasis on fixed points scale invariance and their role in quantum field theory and phase transitions</li><li>Other topics include non-perturbative phenomena anomalies and conformal invariance</li><li>Features numerous examples and extensive problem sets</li><li>Also serves as an invaluable resource for researchers</li></ul>
