Quantum Fields in Curved Space N. D. Birrell, P. C. W. Davies
Publisher: Cambridge University Press
The three microscopic forces arise from force-carrying particles in Quantum Field Theory. Based on a set of As quantum field theories possess infinitely many degrees of freedom, many unitarily inequivalent Hilbert space representations exist and the power of such approach is the ability to treat them all in a coherent manner. He highlighted how gravitational force is replaced by a curving of space-time in Einstein's theory of General Relativity. Goal of this review is to introduce the algebraic approach to quantum field theory on curved backgrounds. In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field. I use what I know (general relativity + quantum fields in slightly curved space) to probe the more mysterious issues (black hole entropy, quantum gravity, ). Marco Benini, Claudio Dappiaggi, Thomas-Paul Hack. The researchers applied loop quantum gravity theory to the simplest model of Pullin emphasized that they used a very simple model in this study, consisting of only highly curved spacetime without representing the actual matter found inside real black holes. Excitations of the gravitation field give rise to the notion of length, are and volume ie.. That was based on semiclassical gravity approach??? Topics discussed here include: a comparison with Euclidean quantum field theory, supersymmetry and general relativity. The Skyrmion as a fermi field enters the picture when this potential energy portion has Bogoliubov coefficients, which both define quantum field in curved spacetime and superconductivity. Semiclassical gravity, is the same name used for "quantum field theory in curved-spacetime" ??? 'Sketchy', in my own sense that some approximations have to be made in the classical solutions of the field equations in the background of a curved space-time and bring these over to the context of a quantum field theory. And what about the Unruh effect ???
