    • Triadic Resonance Instability in finite-width internal gravity wave beams 

      Grayson, Katherine
      Through the use of both experiments and theoretical modelling, this thesis examines the weakly non-linear dynamics of an internal wave beam becoming unstable to Triadic Resonance Instability (TRI). To date, most theoretical ...
    • Conformal Boundaries, SPTs, and the Monopole-Fermion Problem 

      Boyle Smith, Philip (2022-01-29)
      This thesis studies boundary states in spin conformal field theories in two dimensions, and their connection to the monopole-fermion problem in four dimensions, as well as to symmetry-protected topological phases in two ...
    • Sand dune interactions 

      Bacik, Karol
      Sand dunes are coherent sedimentary structures shaped by the shear stress exerted by the overlaying fluid. Natural dunes abundantly populate deserts, river bottoms, sea beds, and even snow fields. They rarely occur in ...
    • Secular Dynamics of Binaries in Stellar Clusters 

      Hamilton, Chris
      The orbital evolution of two bound point masses (a 'binary') perturbed by external tidal forces represents one of the oldest problems in celestial mechanics. Most obviously, tidal perturbations may arise due to an external ...
