This week I have been studying some papers and a seminar by Lorenzo Sindoni and Daniele Oriti on Spacetime as a Bose-Einstein Condensate. I have also been reading a great book ‘The Universe in a Helium Droplet’ by Volovik and a really good PhD Thesis, ‘Appearing Out of Nowhere: The Emergence of Spacetime in… 618 more words

#### 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
