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

Since the gravitational field is determined by the curvature of spacetime, that would mean on small scales, space would not be continuous and smooth, but rather would be violently curved and fluctuating up and down. The professor why we wanted to quantize gravity, in the sense that we want to treat the metric on space-time as a quantum field, as opposed to, for example, just leaving the metric alone, and doing quantum field theory in curved space-time. Shanti's paper was titled Relativity of Scale: Emergence of Quantum Behavior from Space-Time Geometry and Its Implications. Its physics-related activities extend to the fields of academia, research and outreach. 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. Gravitation: the medium of exchange is the metric of space-time itself. Quantum field theory in curved space time. Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. Davies has published over 100 research papers in the fields of black holes, cosmology, and quantum field theory in curved spacetime. His monograph on Quantum Fields in Curved Space, remains a seminal text in the field of quantum gravity. Since there is no complete quantum theory of gravity, they used an already well-accepted approach, called quantum field theory in curved space time(QUIETS). Taking this into effect, then, requires, at the very least, a massive rewriting of quantum mechanics, as it could no longer treat space and time as fixed parameters. Topics discussed here include: a comparison with Euclidean quantum field theory, supersymmetry and general relativity. Gravitons are virtual excitations of the curvature of space-time, treated as a quantum mechanical field.

For light scalar fields, perturbation theory is plagued by infrared divergences which require resummation techniques.
