Toward the emergence of time in quantum gravity
Abstract/Contents
- Abstract
- Space and time are fundamental to our description and understanding of physical laws. But are space and time themselves only approximations to an even more fundamental description of reality? Recent developments in quantum gravity have shown how space can be emergent from more fundamental principles. This dissertation provides a review of tools and results developed over the last five years which shed light on a more fundamental description of time. We first discuss a way of understanding time using quantum information theoretic techniques. These techniques are put to use to study how causality and the arrow of time can emerge from the pattern of entanglement in tensor networks. Next we discuss concrete models of emergent time in quantum gravity, culminating in a non-perturbative model in which both space and time are emergent from random matrices. This model describes low-dimensional de Sitter quantum gravity, which has a positive cosmological constant
