Holographic cosmology and the origin of time

Abstract: Holographic cosmology is a new framework for the very early universe, the period usually associated with inflation. In holographic cosmology the early Universe is described by a three dimensional QFT, and cosmological evolution is mapped to inverse RG flow. In this talk, I will provide an overview of holographic cosmology and then discuss recent work where lattice QFT methods are used to compute the relevant QFT observables. In particular, I will discuss the IR structure of the dual QFT, which is linked to the initial singularity in cosmology, and show how non-perturbative dynamics resolve the IR singularities present in perturbation theory, thus providing a holographic resolution of the Big Bang singularity.
