Testing the imposition of the Spin Foam Simplicity Constraints
Marc Geiller, Karim Noui
We introduce a three-dimensional Plebanski action for the gauge group SO(4). In this model, the field satisfies quadratic simplicity constraints similar to that of the four-dim…

Phase structure of fuzzy black holes
S. Digal, T. R. Govindarajan, Kumar S. Gupta +1
Noncommutative deformations of the BTZ blackholes are described by noncommutative cylinders. We study the scalar fields in this background. The spectrum is studied analytically and…

A new look at Lorentz-Covariant Loop Quantum Gravity
Marc Geiller, Marc Lachieze-Rey, Karim Noui
In this work, we study the classical and quantum properties of the unique commutative Lorentz-covariant connection for loop quantum gravity. This connection has been found after so…
