Abstract

There seems to be a common prejudice that asymptotic safety is either incompatible with, or at best unrelated to, the other topics in the title. This is not the case. In fact, we show that 1) the existence of a fixed point with suitable properties is a promising way of deriving emergent properties of gravity, and 2) there is a sense in which asymptotic safety implies a minimal length. In so doing we also discuss possible signatures of asymptotic safety in scattering experiments.

    • > But I'll chase up some of the ASG references. I recommend the introduction to Class.Quant.Grav.27:245026,2010 DOI: 10.1088/0264-9381/27/24/245026 https://arxiv.org/abs/1008.3621 which is reasonably accessible and high-level in a way that's hard to find for asymptotically safe…
