We devise a technique for defining and computing -point functions in the context of a background-independent gravitational quantum field theory. We construct a tentative implementation of this technique in a perturbatively finite model defined using spin foam techniques in the context of loop quantum gravity. 
Graviton propagator in loop quantum gravity
We compute some components of the graviton propagator in loop quantum gravity, using the spinfoam formalism, up to some second-order terms in the expansion parameter.
Background-free propagation in loop quantum gravity
I review the definition of n-point functions in loop quantum gravity, discussing what has been done and what are the main open issues. Particular attention is dedicated to gauge aspects and
On the structure of a background independent quantum theory: Hamilton function, transition amplitudes, classical limit and continuous limit
The Hamilton function is a powerful tool for studying the classical limit of quantum systems, which remains meaningful in background-independent systems. In quantum gravity, it clarifies the physical
Loop quantum gravity and black hole singularity
In this paper we summarize "loop quantum gravity" (LQG) and we show how ideas developed in LQG can solve the black hole singularity problem when applied to a minisuperspace model.
Introduction to loop quantum gravity
Loop quantum gravity is an attempt to formulate a quantum theory of general relativity. The quantisation is performed in a mathematically rigorous, non-perturbative and background independent manner
The Euclidean three-point function in loop and perturbative gravity
We compute the leading order of the three-point function in loop quantum gravity, using the vertex expansion of the Euclidean version of the new spin foam dynamics, in the region of γ < 1. We find
An Introduction to Loop Quantum Gravity and Its Application to Black Holes by
This paper provides a brief introduction to Loop Quantum Gravity which is the main competitor of String Theory for a quantized theory of gravity. It is formulated on the basis of a Hamiltonian
Lorentzian loop quantum gravity vertex amplitude
We generalize a model recently proposed for Euclidean quantum gravity to the case of Lorentzian signature. The main features of the Euclidean model are preserved in the Lorentzian one. In particular,
Chiral Tensor Power Spectrum from Quantum Gravity
Quantum fluctuations that are produced during inflation freeze out after leaving the horizon and can survive until today, as was described in Sect. 1.2.5.


Free vacuum for loop quantum gravity
We linearize extended ADM gravity around the flat torus, and use the associated Fock vacuum to construct a state that could play the role of a 'free' vacuum in loop quantum gravity. The state we
Introduction to Modern Canonical Quantum General Relativity
This is an introduction to the by now fifteen years old research field of canonical quantum general relativity, sometimes called "loop quantum gravity". The term "modern" in the title refers to the
