Physics of Deformed Special Relativity: Relativity Principle revisited
Florian Girelli, Etera R. Livine
In many different ways, Deformed Special Relativity (DSR) has been argued to provide an effective limit of quantum gravity in almost-flat regime. Some experiments will soon be able…
Special Relativity as a non commutative geometry: Lessons for Deformed Special Relativity
Florian Girelli, Etera R. Livine
Deformed Special Relativity (DSR) is obtained by imposing a maximal energy to Special Relativity and deforming the Lorentz symmetry (more exactly the Poincaré symmetry) to accommod…
Boucles et Mousses de Spin en Gravite Quantique
Etera R. Livine
I review the formalism of loop quantum gravity, in both its real and complex formulations, and spin foam theory which is its path integral counterpart. Spin networks for non-compac…
Causality in spin foam models for quantum gravity
Etera R. Livine, Daniele Oriti
We describe how the Barrett-Crane spin foam model defines transition amplitudes for quantum gravity states and how causality can be consistently implemented in it.
2d manifold-independent spinfoam theory
Etera R. Livine, Alejandro Perez, Carlo Rovelli
A number of background independent quantizations procedures have recently been employed in 4d nonperturbative quantum gravity. We investigate and illustrate these techniques and th…
