Spin-Foam Models and the Physical Scalar Product
Emanuele Alesci, Karim Noui, Francesco Sardelli
This paper aims at clarifying the link between Loop Quantum Gravity and Spin-Foam models in four dimensions. Starting from the canonical framework, we construct an operator P actin…
Tensorial Structure of the LQG graviton propagator
Emanuele Alesci
We review the construction of the tensorial structure of the graviton propagator in the context of loop quantum gravity and spinfoam formalism. The main result of this analysis is…
The complete LQG propagator: II. Asymptotic behavior of the vertex
Emanuele Alesci, Carlo Rovelli
In a previous article we have show that there are difficulties in obtaining the correct graviton propagator from the loop-quantum-gravity dynamics defined by the Barrett-Crane vert…
The complete LQG propagator: I. Difficulties with the Barrett-Crane vertex
Emanuele Alesci, Carlo Rovelli
Some components of the graviton two-point function have been recently computed in the context of loop quantum gravity, using the spinfoam Barrett-Crane vertex. We complete the calc…
