Quantum Gravity and the Functional Renormalization Group

, 2019
During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity.

RENORMALIZATION OF HAMILTONIAN

International Journal of Modern Physics A, 2001
In this talk we describe a novel method for the renormalization of the Hamiltonian operator in Quantum Field Theory in the spirit of the Wilson renormalization group1. By a series of unitary transformations that successively decouple the high-frequency degrees of freedom and partially diagonalizes the high-energy part, we obtain the effective ...

Renormalization Group

1995
The notion of renormalization group is not well defined. It arises in theories in which a prominent role is played by scale invariance or covariance properties, of various quantities, with respect to a noninvertible transformation of coordinates.

Holographic Reconstruction of Spacetime¶and Renormalization in the AdS/CFT Correspondence

, 2000
: We develop a systematic method for renormalizing the AdS/CFT prescription for computing correlation functions. This involves regularizing the bulk on-shell supergravity action in a covariant way, computing all divergences, adding counterterms to cancel

Renormalizing the nonrenormalizable

Physical Review Letters, 1985
A perturbatively nonrenormalizable variant of the Gross-Neveu model of Euclidean quantum field theory with bare propagator p/${\mathrm{p}}^{2\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\epsilon}}}$ is considered. We outline a rigorous argument proving that by appropriate choice of the bare coupling constant the model may be renormalized ...
