Covariant loop gravity comes out of the canonical analysis of the Palatini action and the use of the Dirac brackets arising from dealing with the second class constraints (``simplicity'' constraints). 19 Mar 2018 Manifestly-Covariant Quantum Gravity Theory [20] where the derivation of the Einstein field equation was discussed in the context of loop.

There are a couple of them. You could flip through and start reading the one that suits you or meets your requirements. I list them below: * Quantum Gravity by Carlo Rovelli * Covariant Loop Quantum Gravity by Carlo Rovelli & Francesca Vidotto

RELATING COVARIANT AND CANONICAL APPROACHES TO TRIANGULATED MODELS OF QUANTUM GRAVITY MATTHIAS ARNSDORF Abstract. In this paper explore the relation between covariant and canon-ical approaches to quantum gravity and BF theory. We will focus on the dynamical triangulation and spin-foam models, which have in common that

Quantum gravity as the natural regulator of the Hamiltonian constraint of matter quantum field theories. Class. As we shall see the loop formalism goes far beyond a simple gauge invariant description, in fact it is the natural geometrical framework to treat gauge theories and quantum gravity in terms of their fundamental physical excitations.

The main difference is that these quantum gravity studies assume the quantum laws to be set as fundamental laws. In such a framework, the fractal geometry of space-time at the Planck scale is a consequence of the quantum nature of physical… As the study of the statistical mechanics of black-body radiation led to the advent of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the understanding of… Since the supersymmetry (SUSY) generators form together with the Poincaré algebra a superalgebra, called the super-Poincaré algebra, supersymmetry a gauge theory makes gravity arise in a natural way. The equations governing ordinary gravity in free space can be obtained from an action, by applying the variational principle to a certain action. Some functional forms may be inspired by corrections arising from a quantum theory of gravity. f(R) gravity was first proposed in 1970 by Hans Adolph Buchdahl (although ϕ was used rather than f for the name of the arbitrary function).

Academia.edu is a platform for academics to share research papers. Relativity [7–9]. We will present and use the covariant approach to Loop Quantum Gravity. The covariant approach to Loop Quantum Gravity, or, spinfoam quantization pro-gram, is interlinked, inspired and based on the results of its parent theory, Loop Quan-tum Gravity. The Hamiltonian will in this sense be implicit. How is loop quantum gravity related to the principle of relativity, in particular to the diffeomorphism invariance of general relativity? the thing to focus on is a relatively recent formulation of Lqg called "covariant Lqg". If I google that, I get: and also the Cambridge UP page for the book International Loop Quantum Gravity Seminar. This is a seminar on research that takes place every Tuesday at 9am (US Central Time). Slides of the talks are posted in advance here. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Covariant loop gravity comes out of the canonical analysis of the Palatini action and the use of the Dirac brackets arising from dealing with the second class constraints (“simplicity ” constraints). Within this framework, we underline a quantization ambiguity due to the existence of a family of possible Lorentz Covariant quantum gravity only works in the traditional way up to 1 loop (and together with matter not even then); at higher loops (i.e., for corrections of higher order in the Planck constant hbar) one needs more and more counterterms to make the resulting combination of integrals finite.

For example, classically scale invariant field theories, where scale invariance is broken by quantum effects, provide an explanation of the flatness of inflationary potentials, as long as the theory can be studied through perturbation… The Haag–Kastler axiomatic framework for quantum field theory, introduced by Haag and Kastler (1964), is an application to local quantum physics of C*-algebra theory. The main difference is that these quantum gravity studies assume the quantum laws to be set as fundamental laws.
