Webv. t. e. Asymptotic safety (sometimes also referred to as nonperturbative renormalizability) is a concept in quantum field theory which aims at finding a consistent and predictive quantum theory of the gravitational field. Its key ingredient is a nontrivial fixed point of the theory's renormalization group flow which controls the behavior of ... Gauge theory gravity (GTG) is a theory of gravitation cast in the mathematical language of geometric algebra. To those familiar with general relativity, it is highly reminiscent of the tetrad formalism although there are significant conceptual differences. Most notably, the background in GTG is flat, Minkowski spacetime. The equivalence principle is not assumed, but instead follows from the fact that the gauge covariant derivative is minimally coupled. As in general relativity, equ…

Gravity as the square of gauge theory: a review

WebConsider a gauge theory with gauge group GL(n, R). First of all, let me remind you the basics of gauge transformations: Let G be a gauge group, g(x) ∈ G be an element of G. Then: ψ(x) → g(x)ψ(x) Aα → g(x)Aαg − 1(x) − ∂ g ( x) ∂ xα g − 1(x) is a gauge transformation, and covariant derivative defined as ∇αψ = ∂ ψ ∂ xα + Aαψ WebGravity as the Square of Gauge Theory Michael Kiermaier Princeton University Amplitudes 2010, Queen Mary University of London a a based mainly on arXiv:1004.0693 with Zvi … penylan carpets cardiff
