Tensorial methods and renormalization in Group Field Theories by Sylvain Carrozza

This week I am going to look at a the PhD thesis, Tensorial methods and renormalization in Group Field Theories by  Sylvain Carrozza .

The thesis looks at the two main ways of understanding the construction of GFT models. 696 more words

The 4d Quantum Tetrahedron

We start from the GFT formulation of 4d gravity. Starting from the classical continuum action which is the basis for most model building in LQG… 280 more words

Towards quantum asymptotic flatness

It is of great physical interest to construct a canonical quantization of asymptotically flat spacetimes. The classical phase space variables are subject to delicate boundary conditions at spatial infinity and the first challenge is to construct a quantum kinematics which carries an imprint of these boundary conditions. 456 more words
