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…
A model for the motion of a particle in a quantum background
Karim Noui
We are studying the dynamics of a one-dimensional field in a non-commutative Euclidean space. The non-commutative space we consider is the one that emerges in the context of three…
Three dimensional Loop Quantum Gravity: towards a self-gravitating Quantum Field Theory
Karim Noui
In a companion paper, we have emphasized the role of the Drinfeld double DSU(2) in the context of three dimensional Riemannian Loop Quantum Gravity coupled to massive spinless poin…
Three Dimensional Loop Quantum Gravity: Particles and the Quantum Double
Karim Noui
It is well known that the quantum double structure plays an important role in three dimensional quantum gravity coupled to matter field. In this paper, we show how this algebraic s…
Unfashionable observations about three dimensional gravity
E. Buffenoir, K. Noui
It is commonly accepted that the study of 2+1 dimensional quantum gravity could teach us something about the 3+1 dimensional case. The non-perturbative methods developed in this ca…
