Event Information:

I will start with a review of how General Relativity can be treated as a quantum field theory, as well as some of its limitations. After a general discussion of the Arrow of Causality in QFT, I will turn to gravity with quadratic curvature terms, which is a potential UV completion of General Relativity. This forms a renormalizable QFT, although it is one with some non-standard features. The talk will try to walk us all through some of what is known about these non-standard aspects.
