The foundational chapters are followed by an accessible summary of the results obtained so far. It is the first detailed exposition of asymptotic safety, providing a unique introduction to quantum gravity and it assumes no previous familiarity with the renormalization by: Website created to collect and disseminate knowledge about perturbative quantum field theory and renormalization. Cosmic inflation as a renormalization-group flow: the running of power spectra in quantum gravity J We study the running of power spectra in inflationary cosmology as a renormalization-group flow from the de Sitter fixed point. Renormalization Group (RG) is a powerful method for investigating quantum effects of matter ﬁelds on curved background. The formalism of RG in curved space is well known since , but its applications to cosmology and black hole physics require more knowledge and opens a .
Cosmic inflation as a renormalization-group flow: the running of power spectra in quantum gravity. We study the running of power spectra in inflationary cosmology as a renormalization-group flow from the de Sitter fixed point. The beta function is provided by the equations of the background metric. Book. D. Anselmi From Physics To Life We study the running of power spectra in inflationary cosmology as a renormalization-group flow from the de Sitter fixed point. The beta function is provided (read more) Although the trace anomaly in external gravity is zero in odd dimensions, I show that the odd-dimensional formula has a. The renormalization group was initially devised in particle physics, but nowadays its applications extend to solid-state physics, fluid mechanics, physical cosmology, and even nanotechnology. An early article by Ernst Stueckelberg and André Petermann in anticipates the idea in .

This book, meant for graduate students, gives an original and modern insight into quantum field theory (QFT). Exercises are included. The advanced topics cover renormalization, effective action, fermions, nonabelian gauge theories, beta function of Yang-Mills theory and the strong CP problem. We address the issue of a dynamical breakdown of scale invariance in quantum Weyl gravity together with related cosmological implications. In the first part, we build on our previous work [Phys. Rev. D, , ], where we found a non-trivial renormalization group fixed point in the infrared sector of quantum Weyl gravity. Here, we prove that the ensuing non-Gaussian IR fixed point .
