{"product_id":"physics-of-time-reversal","title":"Physics of Time Reversal","description":"The notion that fundamental equations governing the motions of physical systems are invariant under the time reversal transformation (\u003ci\u003eT\u003c\/i\u003e) has been an important, but often subliminal, element in the development of theoretical physics. It serves as a powerful and useful tool in analyzing the structure of matter at all scales, from gases and condensed matter to subnuclear physics and the quantum theory of fields. The assumption of invariance under \u003ci\u003eT\u003c\/i\u003e was called into question, however, by the 1964 discovery that a closely related assumption, that of \u003ci\u003eCP\u003c\/i\u003e invariance (where \u003ci\u003eC\u003c\/i\u003e is charge conjugation and \u003ci\u003eP\u003c\/i\u003e is space inversion), is violated in the decay of neutral \u003ci\u003eK\u003c\/i\u003e mesons. \u003cbr\u003e\u003cbr\u003eIn \u003ci\u003eThe Physics of Time Reversal\u003c\/i\u003e, Robert G. Sachs comprehensively treats the role of the transformation \u003ci\u003eT\u003c\/i\u003e, both as a tool for analyzing the structure of matter and as a field of fundamental research relating to \u003ci\u003eCP\u003c\/i\u003e violation. For this purpose he reformulates the definitions of \u003ci\u003eT, P,\u003c\/i\u003e and \u003ci\u003eC\u003c\/i\u003e so as to avoid subliminal assumptions of invariance. He summarizes the standard phenomenology of \u003ci\u003eCP \u003c\/i\u003eviolation in the \u003ci\u003eK\u003c\/i\u003e-meson system and addresses the question of the mysterious origin of \u003ci\u003eCP \u003c\/i\u003eviolation. Using simple examples based on the standard quark model, Sachs summarizes and illustrates how these phenomenological methods can be extended to analysis of future experiments on heavy mesons. He notes that his reformulated approach to conventional quantum field theory leads to new questions about the meaning of the transformations in the context of recent theoretical developments such as non-Abelian gauge theories, and he suggests ways in which these questions may lead to new directions of research.","brand":"The University of Chicago Press","offers":[{"title":"Default Title","offer_id":54218516562264,"sku":"9780226733319","price":55.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780226733319.jpg?v=1771308042","url":"https:\/\/agendabookshop.com\/products\/physics-of-time-reversal","provider":"Agenda Bookshop","version":"1.0","type":"link"}
