Quantum Fields in Curved Space N. D. Birrell, P. C. W. Davies
Publisher: Cambridge University Press

If it is a graviton field then it is not the curvature of space-time but the interaction of the graviton force particles. Particle from quantum fields in curved space. Marco Benini, Claudio Dappiaggi, Thomas-Paul Hack. Excitations of the gravitation field give rise to the notion of length, are and volume ie.. If gravity is the curvature of space-time then how can it ever be described by a quantum 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. Title: Symmetries and supersymmetries of the Dirac operators in curved spacetimes. Hu, Shih-Yuin Lin arXiv:hep-th/0411016. Goal of this review is to introduce the algebraic approach to quantum field theory on curved backgrounds. Quantum Einstein Gravity (QEG) is the generic name for any quantum field theory of gravity that (regardless of its bare action) takes the spacetime metric as the dynamical field variable and whose symmetry is given by diffeomorphism invariance. Al., 2009), and the square of the Weyl curvature tensor (Benedetti et. As a postdoctoral fellow at Cambridge University, he worked with Stephen Hawking in cosmology, quantum field theory in curved space time and quantum theories of gravitation. This has been extended further by taking into account polynomials of the scalar curvature \(R\) (so-called \(f(R)\)-truncations) (Codello et.
