Lecture Notes in Physics,0075-8450 ;643Bibliographic Level Mode of Issuance: Monograph3-540-21318-X The intriguing mechanism of spontaneous symmetry breaking is a powerful innovative idea at the basis of most of the recent developments in theoretical physics, from statistical mechanics to many-body theory to elementary particles theory; for infinitely extended systems a symmetric Hamiltonian can account for non symmetric behaviours, giving rise to non symmetric realizations of a physical system. In the first part of this book, devoted to classical field theory, such a mechanism is explained in terms of the occurrence of disjoint sectors and their stability properties and of an improved version of the Noether theorem. For infinitely extended quantum systems, discussed in the second part, the mechanism is related to the occurrence of disjoint pure phases and characterized by a symmetry breaking order parameter, for which non perturbative criteria are discussed, following Wightman, and contrasted with the standard Goldstone perturbative strategy. The Goldstone theorem is discussed with a critical look at the hypotheses that emphasizes the crucial role of the dynamical delocalization induced by the interaction range. The Higgs mechanism in local gauges is explained in terms of the Gauss law constraint on the physical states. The mathematical details are kept to the minimum required to make the book accessible to students with basic knowledge of Hilbert space structures. Much of the material has not appeared in other textbooks.Lecture Notes in Physics,0075-8450 ;643PhysicsQuantum physicsMathematical physicsElementary particles (Physics)Quantum field theoryMathematical Methods in Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19013Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Theoretical, Mathematical and Computational Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19005Elementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Physics.Quantum physics.Mathematical physics.Elementary particles (Physics).Quantum field theory.Mathematical Methods in Physics.Quantum Physics.Theoretical, Mathematical and Computational Physics.Elementary Particles, Quantum Field Theory.530.15Strocchi Francoauthttp://id.loc.gov/vocabulary/relators/aut508801MiAaPQMiAaPQMiAaPQBOOK996466792003316Symmetry Breaking772615UNISA00877nam0-22002771i-450 99000589085040332120240610113231.02-13-046523-4FED01000589085(Aleph)000589085FED0100058908520000421d1994----km-y0itay50------bafrey-------001yy<<Les >>paradigmes de la démocratiesous la direction de Jacques Bidetpublié avec le concours de l'Uniersité de Paris X - NanterrePresses Universitaires de FranceParis1994270 p.22 cmActuel Marx ConfrontationBidet,JacquesITUNINARICAUNIMARCBK990005890850403321192.13 MARK/S 83Bibl.32824FLFBCFLFBCPARADIGMES de la démocratie563024UNINA
