{"product_id":"theory-of-scattering-for-quasifree-particles-a","title":"Theory Of Scattering For Quasifree Particles, A","description":"In this book, the author presents the theory of quasifree quantum fields and argues that they could provide non-zero scattering for some particles. The free-field representation of the quantised transverse electromagnetic field is not closed in the weak*-topology. Its closure contains soliton-anti-soliton pairs as limits of two-photon states as time goes to infinity, and the overlap probability can be computed using Uhlmann's prescription. There are no free parameters: the probability is determined with no requirement to specify any coupling constant. All cases of the Shale transforms of the free field ϕ of the form ϕ→ϕ+φ, where φ is not in the one-particle space, are treated in the book. There remain the cases of the Shale transforms of the form ϕ → Tϕ, where T is a symplectic map on the one-particle space, not near the identity.","brand":"World Scientific Publishing Co Pte Ltd","offers":[{"title":"Default Title","offer_id":54234757890392,"sku":"9789814612067","price":68.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9789814612067_baab8f48-57a7-4ed7-ae37-5d85039f79eb.jpg?v=1777256145","url":"https:\/\/agendabookshop.com\/products\/theory-of-scattering-for-quasifree-particles-a","provider":"Agenda Bookshop","version":"1.0","type":"link"}
