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

Einstein's proposed unified-field equations (fundamental laws of physics) were generally derived from a variational principle expressed in terms of the Riemann curvature tensor for the presumed space-time manifold. Topics discussed here include: a comparison with Euclidean quantum field theory, supersymmetry and general relativity. Obviously space is part of spacetime and so the effect of the curvature of spacetime is usually (but not always) that we can no longer think of space as being flat (mathematically speaking). مخزن کتاب های فیزیک، پایگاه دانلود فیزیک - Quantum Fields in Curved Space - N. Please teach me more detail: why we must consider Quantum Field Theory in Curved Space-Time,but do not consider the QTF Theory(e.g Quantum Electrodynamics) in flat space-time with ''gravity coupling'' (mass). And what about the Unruh effect ??? Davies - دانلود الکترودینامیک، مکانیک کوانتومی، آماری، ترمودینامیک، هسته ای، فیزیک محاسباتی، اخترفیزیک، اپتیک. That was based on semiclassical gravity approach??? In field theories of this kind, particles . The prediction of their existence falls out of the Dirac Equation, but Einstein's model accounts for the negative energy states differently than modern quantum field theory does: Once Upon a Spacetime · 3:58 PM. The noise kernel is the vacuum expectation value of the (operator-valued) stress-energy bitensor, which describes the fluctuations of quantum-matter fields in curved spacetimes.

For light scalar fields, perturbation theory is plagued by infrared divergences which require resummation techniques. I can't do the math, but I suspect that gravity waves from distant events are unlikely to penetrate spacetime that is locally curved by strong gravitational fields. A new improved criterion for the validity of First, we consider metric perturbations in a Minkowski spacetime, compute the two-point correlation functions of these perturbations and prove that Minkowski spacetime is a stable solution of semiclassical gravity. According to the UA physicist, the curvature of space is what makes gravitational mass different from inertial mass. Semiclassical gravity, is the same name used for "quantum field theory in curved-spacetime" ???
