Andrzej KrasinskiThis unique volume provides a comprehensive survey of our understanding of the Universe based on the exact solutions of the theory of relativity. More precisely, it describes those models that fit with astronomical observations of galaxy clusters, cosmic voids and other key features of our Universe. This authoritative account achieves two important goals. First, it collects all independently derived cosmological solutions since the birth of relativity in 1915, and clearly shows how they are interrelated. Second, it presents a coherent overview of the physical properties of these inhomogeneous models. It demonstrates, for instance, that the formation of voids and the interaction of the cosmic microwave background radiation with matter in the Universe can be explained by exact solutions of the Einstein equations, without the need for approximations. This book will be of particular interest to graduates and researchers in gravity, relativity and theoretical cosmology as well as historians of science.

A canonical quantization approach to classical field theory, this text is suitable for mathematicians interested in theoretical physics as well as to theoretical physicists who use differential geometric methods in their modelling. Introduces differential geometry, the theory of Lie groups, and progresses to discuss the systematic development of a covariant Hamiltonian formulation of field theory. 1988 edition.

Howard BaerSupersymmetric models of particle physics predict new superpartner matter states for each particle in the Standard Model. These superpartners will have wide ranging implications, from cosmology to observations at high energy accelerators, such as CERN's LHC. In this text, the authors develop the basic concepts of supersymmetry and show how it can be incorporated into a theoretical framework for describing unified theories of elementary particles. They develop the technical tools of supersymmetry using four-component spinor notation familiar to high energy experimentalists and phenomenologists. The text takes the reader from an abstract formalism to a straightforward recipe for writing supersymmetric gauge theories of particle physics, and ultimately to the calculations necessary for practical applications at colliders and in cosmology. This is a comprehensive, practical and accessible introduction to supersymmetry for experimental and phenomenological particle physicists and graduate students. Exercises and worked examples that clarify the material are interspersed throughout. Develops very general supersymmetric models for the interactions of elementary particles from basic principles Uses 4-component spinor notation to develop the superfield formalism (a necessary technical tool) Extensively treats the experimental implications of supersymmetry Contains over 100 exercises and worked examples throughout the text

Quantum information and computation is a rapidly expanding and cross-disciplinary subject. This book gives a self-contained introduction to the field for physicists, mathematicians and computer scientists who want to know more about this exciting subject. After a step-by-step introduction to the quantum bit (qubit) and its main properties, the author presents the necessary background in quantum mechanics. The core of the subject, quantum computation, is illustrated by a detailed treatment of three quantum algorithms: Deutsch, Grover and Shor. The final chapters are devoted to the physical ...

Differential geometry plays an increasingly important role in modern theoretical physics and applied mathematics. This textbook gives an introduction to geometrical topics useful in theoretical physics and applied mathematics, covering: manifolds, tensor fields, differential forms, connections, symplectic geometry, actions of Lie groups, bundles, spinors, and so on. Written in an informal style, the author places a strong emphasis on developing the understanding of the general theory through more than 1000 simple exercises, with complete solutions or detailed hints. The book will prepare readers for studying modern treatments of Lagrangian and Hamiltonian mechanics, electromagnetism, gauge fields, relativity and gravitation. Differential Geometry and Lie Groups for Physicists is well suited for courses in physics, mathematics and engineering for advanced undergraduate or graduate students, and can also be used for active self-study. The required mathematical background knowledge does not go beyond the level of standard introductory undergraduate mathematics courses.

Eduard A. Tropp, Viktor Ya Frenkel, Artur D. CherninA vivid account of the life and work of the Russian physicist responsible for the expanding universe theory.Our universe can be described mathematically by a simple model developed in 1922 at Petrograd (St Petersburg) by Alexander Friedmann (18881925), who predicted that the whole universe would expand and evolve with time before there was any observational evidence. He was an outstanding Soviet physicist, and this vivid biography is set in a wide historical background. The book is a window on the school and university years, military service, teaching and research during a seminal period of Soviet history. The authors include unique archival material, such as Friedmanns letters from the Front, as well as contemporary records and reminiscences of colleagues. There is a detailed treatment of his work in Theoretical Cosmology (19221924), set in the context of the organization of Soviet science at the time. The only account of the person who first suggested that our universe is expanding and evolving A fascinating glimpse of the organization of higher education and science in the period 19171924 Includes unpublished archival material and personal letters

La geometría más dura, la de probar que "tales puntos están alineados" o que "tales rectas son concurrentes", no es la única geometría interesante. Existe otra geometría mucho más cercana, mucho más amable, que reúne todas las características de conjeturar y deducir que debería tener toda actividad matemática. Ésta es la geometría que se refleja en los problemas que se presentan en este libro. En él los aficionados a las matemáticas y los estudiantes de los últimos cursos de ESO y de bachillerato podrán ponerse a prueba y enfrentarse a los problemas de geometría más interesantes. Y como, según Pushkin, la geometría exige tanta inspiración como la poesía, si la primera fallara, podrán analizar la solución que proponemos.

Partha GhoseTechnological advances have made it possible to perform experiments, once considered to be purely gedanken, which test the counterintuitive and bizarre consequences of quantum theory. This book provides simple accounts of these experiments and an understanding of what they aim to prove and why this is important. After introducing the main theoretical concepts and problems with the foundations of quantum mechanics, early chapters discuss experiments in the areas of wave-particle duality, cavity quantum electrodynamics and quantum non-demolition measurement. The text then examines investigation of certain predictions including the Aharanov-Bohm effect, before tackling the problem of macroscopic quantum coherence. Later chapters consider methods of testing the quantum Zeno paradox, collapse, macroscopic quantum jumps, tunnelling times and Einstein-Bell non-locality. Introductions to the theory behind types of measuring devices such as micromasers and those based on the concept of quantum non-demolition are also given. Detailed references are included. Up to date and accessible Suitable as an introduction for graduate students

Motivaciones geométricas llevaron a Sophus Lie, matemático noruego, a crear y desarrollar, a través del estudio de las simetrías de las ecuaciones en derivadas parciales, la teoría de grupos que hoy lleva su nombre y que es ampliamente utilizada en fisica y en muchas ramas de las matematicas. La importancia de las simetrias radica en que son suficientes para reducir sustancialmente la resolucion de dichas ecuaciones diferenciales, algo en lo que Lie cayo en cuenta trabajando con las superficies de Plucker.Jose Luis Guijarro Regalado se licencio en matematicas en la UAM y obtuvo el Diploma de Estudios Avanzados en la UCM por su trabajo sobre la clasificacion de subvariedades Cen geometria de Lie y geometria de Plucker. Actualmente, es profesor asociado en la Facultad de Matematicas de la UCM.

Carlo RovelliBook presenting the loop and spinfoam approach to quantum gravity, for graduates and researchers. Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time.
