Gravitational Waves from a Quantum Field Theory Perspective

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.
