Quantum field theory on curved spacetime , Lecture notes in physics, Springer (2009). [2][3] Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. Its physics-related activities extend to the fields of academia, research and outreach. In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field. Title: Symmetries and supersymmetries of the Dirac operators in curved spacetimes. Hu, Shih-Yuin Lin arXiv:hep-th/0411016. The fancy new piece of machinery (by then an old hat for string theorists and a really old hat for relativists) was the spin connection which allows us to connect the flat-space formalism for spinors to curved spaces. I use what I know (general relativity + quantum fields in slightly curved space) to probe the more mysterious issues (black hole entropy, quantum gravity, ). While quantum mechanics may be formulated for a wide range of physical systems, interpreted as particles, extended particles and fields, the quantum mechanics of fields is often called the quantum field theory and the quantum mechanics of systems of a fixed finite number of particles is often view as the quantum mechanics in a narrow sense. Peter: Have you by any chance read this paper by Robert Wald “The Formulation of Quantum Field Theory in Curved Spacetime.” http://arxiv.org/abs/0907.0416 ? Black hole evaporation is an effect of quantum field theory in curved spacetime. Despite of it, the combination of four-dimensional general relativity and quantum mechanics theories can describe some aspects of five-dimensional reality like the small curved patches, which are used for paving of rough surface. From the previous post, we'll follow on from the general idea of an accelerating quantum vacuum composed of virtual particles interacting with mass which we perceive as gravity (spacetime curvature) and responsible for The diagram below shows the situation quite well for a particle with charge q, velocity v, and the effect of the Lorentz force on this test charge (negative, positive or neutral) due to a magnetic field B coming out of the screen perpendicular to you. This Amrita talk was the only presentation from “Around sufficiently small particles space-time can be substantially curved giving rise to time dilation and space contraction effects as with particles moving at high velocities. First to show how to place fermion fields in the bulk. Particle from quantum fields in curved space. Spacetime analogs is an emerging field of physics in which scientists investigate systems having mathematical links with general relativity, and test their theories about the early behavior of the universe. Shanti's paper was titled Relativity of Scale: Emergence of Quantum Behavior from Space-Time Geometry and Its Implications. 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. It's not a quantum gravitational effect, that's the exact reason why it's been dissected since decades. For more information about the spin connection in the language of quantum field theory, Bertlemann's “Anomalies in Quantum Field Theory” seems very comprehensive.
