Available in PDF, EPUB and Kindle. Book excerpt: The motivation of this thesis is to look for a signature of Lorentz violation, hopefully observable, in the gravitational waves emitted by cosmic strings. Aspects of cosmic strings are reviewed, in particular how focused bursts of gravitational radiation are emitted when a cusp forms on the string. The same phenomenon is then studied in an effective field theory with Lorentz violation called Einstein-aether theory. This is a simple theory with a dynamic preferred frame, but it retains rotational and diffeomorphism invariance. The linearized version of the theory produces five wave modes. We study the usual transverse traceless modes which now have a wave speed that can be lower or greater than the speed of light. This altered speed produces distinctive features in the waves. They depend on two free parameters: roughly the wave speed and the acceleration of the string cusp. The profile of the wave is analyzed in detail for different values of the parameters and explained by close comparison with the string motion.

Download or read book Spacetime and Gravitation written by Wojciech Kopczynski and published by . This book was released on 1992-01-30 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ideas about space and time are at the root of one's understanding of nature, both at the intuitive level of everyday experience and in the framework of sophisticated physical theories. These ideas have led to the development of geometry and its applications to physics. The contemporary physical theory of space and time, including its extention to the phenomena of gravitation, is Einstein's theory of relativity. Spacetime and Gravitation is a short introduction to this theory. It is addressed to a fairly wide readership: parts of it can be read by university students of mathematics, physics and engineering. A great deal of emphasis is given to the geometrical aspects of relativity theory and its comparison with the Newtonian view of the world. There are short chapters on the origins of Einstein's theory, gravitational waves, cosmology, spinors and the Einstein-Cartan theory.
Download or read book Gravitational Waves Explained written by Richard Gaughan and published by Enslow Publishing, LLC. This book was released on 2018-12-15 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September of 2015, the scientific world was buzzing: gravitational waves had been detected. It was a dramatic and conclusive demonstration of Einstein's theory of general relativity, the most complex and far-reaching theory in the history of physics. Through detailed diagrams, relatable analogies, and informative sidebars, this text cuts through the complexity and sophistication, providing an accessible introduction to the physics of waves, the implications of general relativity, and the ways in which gravitational waves can bring new understanding of the universe around us.

Download or read book Strings and Gravity written by Marc Henneaux and published by De Boeck Supérieur. This book was released on 2003-03-13 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: La théorie de la gravitation d'Einstein ("relativité générale") est un des piliers de la physique moderne. Cette théorie a connu des développements spectaculaires ces dernières années, aussi bien sur le plan expérimental que sur le plan théorique. En particulier, la théorie des cordes, née il y a une quinzaine d'années, offre des perspectives remarquables d'unification de la force gravitationnelle aux autres forces fondamentales - réalisant ainsi un des vieux rêves d'Einstein. Cet ouvrage rassemble les contributions des experts mondiaux du domaine ayant participé au colloque Francqui qui s'est tenu sur ce thème à Bruxelles du 19 au 21 octobre 2001. Einstein theory of gravity is one of the pillars of modern physics. In the last years, this theory has undergone dramatic developments, both on the experimental and theoretical sides. In particular, string theory, which started in the last quarter of the XXth century, offers remarkable prospects to unify all the fundamental interactions - realizing thereby one of the Einstein's dreams. This book contains the contributions of the world leaders in the field who took part in the "Francqui conference" held on this theme in Brussels in October 2001.

Download or read book Gravitational Waves written by Carlos Frajuca and published by Intechopen. This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravitational waves were predicted by Albert Einstein in his most famous theory, the general theory of relativity, but it took almost a century for these waves to be detected and their existence proven. This book introduces gravitational waves and discusses some of their applications in five dimensions, this is all done in classical gravity. It also explains gravitational waves in quantum gravity (in which the universe is considered to be not continuous) and implications for trying to understand and explore dark energy and an expanding accelerated universe.

Download or read book Gravitational Waves from a Quantum Field Theory Perspective written by Subhendra Mohanty and published by Springer Nature. This book was released on 2023-05-31 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the subject of gravitational waves (GWs) production in binary stars or black-holes and in the early universe, using tools of quantum field theory which are familiar to graduate students and researchers in particle physics. A special focus is given to the generation of templates of gravitational wave signals from Feynman diagram calculations of transition amplitudes, which interests active researchers in GWs. The book presents field theory concepts, like supersymmetry realized in spinning binaries and soft-graviton theorems, that can have practical applications in novel GW signals, like the memory effect. The book also aims at specialists in both GWs and particle physics addressing cosmological models of phase transition and inflation that can be tested in observations at terrestrial and space based interferometers, pulsar timing arrays, and the cosmic microwave anisotropy observations.

Download or read book Aether and Gravitation written by William George Hooper and published by Good Press. This book was released on 2019-12-05 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, like others from the late 19th and early 20th centuries, explores the connection between physics research and electromagnetism. While gravitational effects are also discussed, much of the work focuses on electromagnetic effects. It is intriguing to ponder why this emphasis existed and whether physics has advanced in the right direction since that time. The book provides a glimpse into the scientific thinking of the past and raises questions about the evolution of scientific thought over time.
