Renormalization concepts have been recently shown to be essential for the formulation and understanding of background independent theories such as quantum gravity, as well as for extracting physical predictions from such theories. The workshop will discuss and review recent advances on this topic, both on the conceptual and technical side. It aims to intensify and start collaborations among the different groups working on renormalization, in particular in loop quantum gravity, spin foams and group field theory.

A chain of geometries
The path integral is a very elegant formulation of quantum theory. It can also be an incredibly useful one, since it allows us to use methods of statistical physics, like computer simulations.
In this talk I will introduce the subject of Markov Chain Monte Carlo simulations to solve the path integral over geometries. This general introduction will use examples from Causal Dynamical Triangulations, Causal Set Theory and Non Commutative geometry to show how different issues can be explored in this manner.

Gravitational Casimir Effect
I will derive the gravitonic Casimir effect with non-idealized boundary conditions. This allows the quantification of the gravitonic contribution to the Casimir effect from real bodies. I will show how to use this formula to calculate the meagre gravitonic Casimir effect in ordinary matter. I will also apply this formula to the speculated Heisenberg-Couloumb (HC) effect in superconductors, thereby providing a test for the validity of the HC theory, and, consequently, the existence of gravitons.

Tensor network renormalization
I will present a pedagogical introduction on the application of tensor networks to the renormalization group. This program has resulted in a non-perturbative, real-space RG approach for lattice systems and the multi-scale entanglement renormalization ansatz (MERA). The MERA is currently of interest in a wide range of research areas, from statistical mechanics to condensed matter, from quantum field theory to holography in quantum gravity.
