Loop Quantum Gravity with a cosmological constant
Loop Quantum Gravity is a proposal for a nonperturbative and diffeomorphism invariant canonical quantization of general relativity which leads to remarkable conclusions about the structure of space and time at the Planck scale. Similarly to the discreteness obtained in standard quantum theory from quantization of classical systems the loop quantization of general relativity leads to a discrete structure of space itself. Taking into account that we observe in our universe a nonvanishing positive cosmological constant one certainly wants to implement it in our quantum theory of gravity and then ask how it affects the quantum structure of space and time.
The objective of my research is to understand how quantum groups can arise in Loop Quantum Gravity and how exactly they capture the presence of a cosmological constant. This entails already at the classical level many interesting mathematical questions concerning generalized (quasi) Poisson manifolds and their subsequent quantization. In the quantum theory we aim to utilize so called tensor operators to construct observables and probe the quantum geometry of constantly curved `atoms of space'.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
