Field Theory, The Renormalization Group, And Critical Phenomena: Graphs To Computers (3rd Edition)

• Pertinent Concepts and Ideas in the Theory of Critical Phenomena; Formulation of the Problem of Phase Transitions in Terms of Functional Integrals; Functional Integrals in Quantum Field Theory; Perturbation Theory and Feynman Graphs; Vertex Functions and Symmetry Breaking; Expansions in the Number of Loops and Components; Renormalization; The Renormalization Group and Scaling the Critical Region; The Computation of the Critical Exponents; Beyond Leading Scaling; Universality Revisited; Critical Behavior with Several Couplings; Crossover Phenomena; Critical Phenomena near Two Dimensions; Real Space Methods; Finite Size Scaling; Monte Carlo Methods. Numerical Field Theory.

"Recommended as the core text for any introductory course on field theory." American Scientists (USA) "There are only very few textbooks on the intermediate level, and the first edition of Amit's work has been a very useful one. The second edition with a detailed exposition on finite size scaling, universality and the critical behavior with several coupling constants promises to be a valuable tool in the library of many physicists."
