{"product_id":"9781139931069","title":"Quantum Field Theory in Condensed Matter Physics","description":"This book is a course in modern quantum field theory as seen through the eyes of a theorist working in condensed matter physics. It contains a gentle introduction to the subject and therefore can be used even by graduate students. The introductory parts include a derivation of the path integral representation, Feynman diagrams and elements of the theory of metals including a discussion of Landau–Fermi liquid theory. In later chapters the discussion gradually turns to more advanced methods used in the theory of strongly correlated systems. The book contains a thorough exposition of such non-perturbative techniques as 1\/N-expansion, bosonization (Abelian and non-Abelian), conformal field theory and theory of integrable systems. The book is intended for graduate students, postdoctoral associates and independent researchers working in condensed matter physics.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":47122069618928,"sku":"9781139931069","price":32.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781139931069_p0.jpg?v=1763700614","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781139931069","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
