Origin of the quantum group symmetry in 3d quantum gravity
Maïté Dupuis, Laurent Freidel, Florian Girelli +2
It is well-known that quantum groups are relevant to describe the quantum regime of 3d gravity. They encode a deformation of the gauge symmetries parametrized by the value of the c…
Timelike twisted geometries
Julian Rennert
Within the twistorial parametrization of Loop Quantum Gravity we investigate the consequences of choosing a spacelike normal vector in the linear simplicity constraints. The amplit…
Anisotropic Spinfoam Cosmology
Julian Rennert, David Sloan
The dynamics of a homogeneous, anisotropic universe are investigated within the context of spinfoam cosmology. Transition amplitudes are calculated for a graph consisting of a sing…
A Homogeneous Model of Spinfoam Cosmology
Julian Rennert, David Sloan
We examine spinfoam cosmology by use of a simple graph adapted to homogeneous cosmological models. We calculate dynamics in the isotropic limit, and provide the framework for the a…
