    • Aspects of Quantum Information and AdS/CFT Duality 

      Al Balushi, Abdulrahim (University of Waterloo, 2021-05-17)
      This thesis considers four different aspects of quantum information, AdS/CFT duality, and the interplay between them. First, we study the holographic complexity conjectures in detail for rotating black holes. We focus ...
    • Aspects of Scattering Amplitudes and Moduli Space Localization 

      Mizera, Sebastian (University of Waterloo, 2019-08-19)
      We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ...
