Non-perturbative quantum gravity seen from the lattice
14 Jun 2010, 16:30 – 17:30

I will report on an attempt to define non-perturbatively a theory of quantum gravity. The existence of such a theory has been linked to the "asymptotic safety" scenario first discussed by S. Weinberg. The present attempt to define the quantum gravity constructively from a lattice regularized path integral, (denoted "causal dynamical triangulation") should be seen in that context. I will decribe how we seemingly see the emergence of a 4d world, not really put in by hand, and how the approach might be connected to the so-called Lifshitz gravity, introduced recently by P. Horava.
