Study of cosmological perturbations and derivation of observables in Loop Qua...
General relativity describes gravity as a deformation of space-time. Applied to the Universe as a whole, it explains well cosmological observations in the lambda-CDM... -
Tensorial methods and renormalization in Group Field Theories
In this thesis, we study the structure of Group Field Theories (GFTs) from the point of view of renormalization theory.Such quantum field theories are found in... -
The Chiral Structure of Loop Quantum Gravity
Loop gravity is a tentative theory to describe what happens at the Planck scale, the scale at which both general relativity and quantum theory become equally... -
