Exact Renormalisation Group Equations and Loop Equations for Tensor Models
Thomas Krajewski, Reiko Toriumi
In this paper, we review some general formulations of exact renormalisation group equations and loop equations for tensor models and tensorial group field theories. We illustrate t…
Polchinski's exact renormalisation group for tensorial theories: Gaussian universality and power counting
Thomas Krajewski, Reiko Toriumi
In this paper, we use the exact renormalisation in the context of tensor models and tensorial group field theories. As a byproduct, we rederive Gaussian universality for random ten…
Path Integral Representation of Lorentzian Spinfoam Model, Asymptotics, and Simplicial Geometries
Muxin Han, Thomas Krajewski
A new path integral representation of Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model is derived by employing the theory of unitary representation of SL(2,$\mathbb{C}…
Group field theories
Thomas Krajewski
Group field theories are particular quantum field theories defined on D copies of a group which reproduce spin foam amplitudes on a space-time of dimension D. In these lecture note…
Cosmological constant in spinfoam cosmology
Eugenio Bianchi, Thomas Krajewski, Carlo Rovelli +1
We consider a simple modification of the amplitude defining the dynamics of loop quantum gravity, corresponding to the introduction of the cosmological constant, and possibly relat…
Quantum Corrections in the Group Field Theory Formulation of the EPRL/FK Models
Thomas Krajewski, Jacques Magnen, Vincent Rivasseau +2
We investigate the group field theory formulation of the EPRL/FK spin foam models. These models aim at a dynamical, i.e. non-topological formulation of 4D quantum gravity. We intro…
