Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the relationship between gravitation and elementary particle physics, and the implications of these subjects for astrophysics. There has, in recent years, been renewed interest in theories that connect up gravitation and particle physics, and in the astrophysical consequences of such theories. Some of these accounts involve a time-variation of the Newtonian gravitational parameter, G. In this respect, the present book may be regarded as a companion to my Cosmology and Geophysics (Hilger, Bristol, 1978). There is some overlap as regards the discussion of G-variability, but the emphasis in the present book is on astrophysics while the emphasis in the other one is on geophysics. The subject is a very broad one indeed, and in giving a review of it I have adopted a somewhat unorthodox way of presenting the material involved. The main reason for this is that a review of such a wide subject should aim at two levels: the level of the person who is interested in it, and the level of the person who is professionally engaged in research into it. To achieve such a two-level coverage, I have split the text up into two parts. The first part (Chapters 1-7) represents a relatively non-technical overview of the subject, while the second part (Chapters 8-11) represents a technical examination of the most important aspects of non-Einsteinian gravitational theory and its relation to astrophysics.

This book was released on 2021-09-27 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book seeks to present a new way of thinking about the interaction of gravitational fields with quantum systems. Despite the massive amounts of research and experimentation, the myriad meetings, seminars and conferences, all of the articles, treatises and books, and the seemingly endless theorization, quantization and just plain speculation that have been engaged in regarding our evolving understanding of the quantum world, that world remains an enigma, even to the experts. The usefulness of general relativity in this regard has proven to be imperfect at best, but there is a new approach. We do not simply have to accept the limitations of Einstein's most celebrated theorem in regard to quantum theory; we can also embrace them, and thereby utilize them, to reveal new facts about the behavior of quantum systems within inertial and gravitational fields, and therefore about the very structure of space–time at the quantum level. By taking existing knowledge of the essential functionality of spin (along with the careful identification of the omnipresent inertial effects) and applying it to the quantum world, the book gives the reader a much clearer picture of the difference between the classical and quantum behaviors of a particle, shows that Einstein's ideas may not be as incompatible within this realm as many have come to believe, sparks new revelations of the way in which gravity affects quantum systems and brings a new level of efficiency—quantum efficiency, if you will—to the study of gravitational theory.

This book was released on 2007-10-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here it is, in a nutshell: the history of one genius’s most crucial work – discoveries that were to change the face of modern physics. In the early 1900s, Albert Einstein formulated two theories that would forever change the landscape of physics: the Special Theory of Relativity and the General Theory of Relativity. Respected American academic Professor Tai Chow tells us the story of these discoveries. He details the basic ideas of Einstein, including his law of gravitation. Deftly employing his inimitable writing style, he goes on to explain the physics behind black holes, weaving into his account an explanation of the structure of the universe and the science of cosmology.

Download or read book Experimental Search for Quantum Gravity written by Sabine Hossenfelder and published by Springer. This book was released on 2017-11-15 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes recent developments in the research area of quantum gravity phenomenology. A series of short and nontechnical essays lays out the prospects of various experimental possibilities and their current status. Finding observational evidence for the quantization of space-time was long thought impossible. In the last decade however, new experimental design and technological advances have changed the research landscape and opened new perspectives on quantum gravity. Formerly dominated by purely theoretical constructions, quantum gravity now has a lively phenomenology to offer. From high precision measurements using macroscopic quantum oscillators to new analysis methods of the cosmic microwave background, no stone is being left unturned in the experimental search for quantum gravity. This book sheds new light on the connection of astroparticle physics with the quantum gravity problem. Gravitational waves and their detection are covered. It illustrates findings from the interconnection between general relativity, black holes and Planck stars. Finally, the return on investment in quantum-gravitation research is illuminated. The book is intended for graduate students and researchers entering the field.

Download or read book Special Relativity in General Frames written by Éric Gourgoulhon and published by Springer Science & Business Media. This book was released on 2013-08-20 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Special relativity is the basis of many fields in modern physics: particle physics, quantum field theory, high-energy astrophysics, etc. This theory is presented here by adopting a four-dimensional point of view from the start. An outstanding feature of the book is that it doesn’t restrict itself to inertial frames but considers accelerated and rotating observers. It is thus possible to treat physical effects such as the Thomas precession or the Sagnac effect in a simple yet precise manner. In the final chapters, more advanced topics like tensorial fields in spacetime, exterior calculus and relativistic hydrodynamics are addressed. In the last, brief chapter the author gives a preview of gravity and shows where it becomes incompatible with Minkowsky spacetime. Well illustrated and enriched by many historical notes, this book also presents many applications of special relativity, ranging from particle physics (accelerators, particle collisions, quark-gluon plasma) to astrophysics (relativistic jets, active galactic nuclei), and including practical applications (Sagnac gyrometers, synchrotron radiation, GPS). In addition, the book provides some mathematical developments, such as the detailed analysis of the Lorentz group and its Lie algebra. The book is suitable for students in the third year of a physics degree or on a masters course, as well as researchers and any reader interested in relativity. Thanks to the geometric approach adopted, this book should also be beneficial for the study of general relativity. “A modern presentation of special relativity must put forward its essential structures, before illustrating them using concrete applications to specific dynamical problems. Such is the challenge (so successfully met!) of the beautiful book by Éric Gourgoulhon.” (excerpt from the Foreword by Thibault Damour)

Download or read book Cosmology and Particle Astrophysics written by L. Bergstrom and published by . This book was released on 1999 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been an increasing realisation that there are important areas of 'common ground' between modern particle physics and high-energy astrophysics. This book provides a much needed, readable yet comprehensive overview of particle physics, and emphasises the close links between particle physics and cosmology. Beginning with some basic facts about the observable universe, the authors consider, in successive chapters, special and general relativity, gravitational lenses, cosmological models, particles and fields, thermodynamics and phase transitions in the early universe. The cosmic microwave background, structure formation and dark matter, the inflationary universe, gamma rays, cosmic rays, neutrinos and gravitational wave detectors are then discussed. Recent discoveries, such as neutrino mass and oscillations, and measurements of the universe using supernovae, are treated in a pedagogical and non-technical manner. A feature of this book is that it is 'self-contained, in that no specialised knowledge is required on the part of the reader except basic undergraduate mathematics and physics. In addition to the more descriptive sections where the reader is able to get the 'flavour' of the subject without needing to follow every step involved, some chapters contain optional, more technical parts which may be skipped by less advanced readers. By combining the expertise of both a leading experimentalist and foremost theorist, this book includes important aspects of both observational cosmology as well as more theoretical concepts. Readership: Undergraduate and postgraduate students of astronomy, astrophysics, cosmology, particle physics, theoretical physics and mathematical physics, and those carrying out research in these fields. Lars Bergström is Associate Professor in the Department of Physics at Stockholm University. He has authored or co-authored over 100 technical articles and scientific papers on physics in general and particle physics in particular. Ariel Goobar is Postdoctoral Research Fellow in Experimental Particle Astrophysics at FYSIKUM, Stockholm University, Sweden. As active researchers in the subjects of high-energy neutrino astrophysics and cosmology, both authors are internationally respected authorities in the field of particle astrophysics.

Download or read book Cosmology and Particle Physics written by V. de Sabbata and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a steadily increasing cross-fertilization between cosmology and particle physics, on both the theoretical and experimental levels. Particle physics has provided new experimental data from the big accelerators in operation, and data from space satellites are accumulating rapidly. Cosmology is still one of the best laboratories for testing particle theory. The present work discusses such matters in the context of inflation, strings, dark matter, neutrinos and gravitational wave physics in the very early universe, field theory at the Planck scale, and high energy physics. A particular emphasis has been placed on a new topology for spatial infinity, on the relation between temperature and gravitational potential, a canonical formulation of general relativity, the neutrino mass, spin in the early universe, the measurement of gravity in the 10--100 m range, galaxy--galaxy and cluster--cluster correlation, black holes, string theory and string/string duality. The work also presents a beautiful review of high energy elementary particle physics, treating the meaning, status and perspectives of unification and standard model gauge couplings.

Moreover, general relativity has important applications in astrophysics and high-energy particle physics. Covering the fundamentals of the subject, Principles of Cosmology and Gravitation describes the universe as revealed by observations and presents a theoretical framework to enable important cosmological formulae to be derived and numerical calculations performed. Avoiding elaborate formal discussions, the book presents a practical approach that focuses on the general theory of relativity. It examines different evolutionary models and the gravitational effects of massive bodies. The book also includes a large number of worked examples and problems, half with solutions.

Download or read book Cosmology Gravitational Waves and Particles written by Fritzsch Harald and published by World Scientific. This book was released on 2017-11-24 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 2016, physicists announced the breakthrough discovery of the gravitational waves, which were predicted by Albert Einstein in his century-old theory of General Relativity. These gravitational waves were emitted as a result of the collision of two massive black holes that happened about 1.3 billion years ago. They were discovered at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States and thus marked a new milestone for physics. However, it remains unclear to physicists how the gravitational interaction can be included in the Standard Theory of particle physics which describes the electroweak and the strong interactions in our universe. In this volume are the lectures, given by the speakers at the conference on cosmology and particle physics. The discussed topics range from gravitational waves to cosmology, dark matter, dark energy and particle physics beyond the Standard Theory.

Download or read book Gravitation written by I. Ciufolini and published by CRC Press. This book was released on 2004-10-31 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early universe. While particle physics offers insight to early universe physics, there is a need to understand gravity at extremes of large and short distances to further understand cosmology and the development of the universe. Gravitation: From the Hubble Length to the Planck Length fulfills this need by providing an overview of relativistic astrophysics, early universe physics, cosmology, and their interface with particle physics. Written by international experts, this reference presents up-to-date information on classical relativity, astrophysics, and theoretical and experimental particle physics. The introduction sets the scene and provides a context for the remaining chapters. Chapters cover an extensive array of topics, from refined experimental techniques in gravitational physics to cosmology and the quantum frontier. The book concludes with a discussion of the connection among particles, fields, strings, and branes. This compilation shows how gravity plays a fundamental role in astronomy, astrophysics, and cosmology by exploring domains from the microscopic, such as black holes, to superclusters of galaxies that form the large-scale texture of the present-day cosmos. Moreover, with its theoretical and experimental focus on the foundations of gravity, Gravitation proves to be an invaluable resource for current and future research.

Download or read book Particle and Astroparticle Physics written by Utpal Sarkar and published by CRC Press. This book was released on 2007-12-03 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: From superstring theory to models with extra dimensions to dark matter and dark energy, a range of theoretically stimulating ideas have evolved for physics beyond the standard model. These developments have spawned a new area of physics that centers on the interplay between particle physics and cosmology—astroparticle physics. Providing the necessary theoretical background, Particle and Astroparticle Physics clearly presents the many recent advances that have occurred in these fields. Divided into five parts, the book begins with discussions on group and field theories. The second part summarizes the standard model of particle physics and includes some extensions to the model, such as neutrino masses and CP violation. The next section focuses on grand unified theories and supersymmetry. The book then discusses the general theory of relativity, higher dimensional theories of gravity, and superstring theory. It also introduces various novel ideas and models with extra dimensions and low-scale gravity. The last part of the book deals with astroparticle physics. After an introduction to cosmology, it covers several specialized topics, including baryogenesis, dark matter, dark energy, and brane cosmology. With numerous equations and detailed references, this lucid book explores the new physics beyond the standard model, showing that particle and astroparticle physics will together reveal unique insights in the next era of physics.
