Towards higher dimensional quantum geometries — •Johannes Thürigen — Albert-Einstein-Institut Potsdam

One way to a quantum description of spacetime geometry is random geometries as generated by matrix and tensor models. Since tensors of rank D come naturally with an interpretation as D-dimensional spacetime manifolds they are a in fact a proposal for D=4 dimensional quantum gravity. Nevertheless, despite huge progress in the understanding of tensor models in recent years, only tree-like and planar regimes have been identified in their 1/N expansion until now. In this contribution we will present a particular tensor model which raises the hope that it will become possible to control also regimes of effective higher dimensionality.
