    • Mapping galaxy components with kinematics : dynamical models with stellar and gaseous kinematics 

      Yang, Meng (University of St Andrews, 2020-12-01) - Thesis
      Mapping galaxy mass distribution is an important means of understanding galaxy morphology and the nature of dark matter haloes, and therefore build up our knowledge of galaxy formation and evolution. Analytical and ...

    • Nonlinear optical eigenmodes : perturbative approach for classical fields and single photons 

      Docherty-Walthew, Graeme Scott (University of St Andrews, 2020-12-01) - Thesis
      In linear optics, the concept of a mode or eigenmode is well established. Often these modes correspond to a set of fields that are mutually orthogonal with intensity profiles that are invariant as they propagate through a ...

    • Agile quantum cryptography and non-classical state generation 

      Thornton, Matthew (University of St Andrews, 2020-12-01) - Thesis
      In the first half of this Thesis, we introduce a framework of “quantum cryptographic agility,” which allows for a resource-efficient swap of an underlying cryptographic protocol. Specifically, we introduce several schemes ...

    • Phase transitions in two-dimensional itinerant electron systems 

      Trott, Matthew J. (University of St Andrews, 2020-12-01) - Thesis
      The aim of this thesis it to contribute to three open problems in the theory of itinerant electron systems in two spatial dimensions. Firstly, the mechanism for charge density wave formation in the transition metal ...

    • Photonic crystal cavity based optical induced transparency 

      Hu, Changyu (University of St Andrews, 2020-12-01) - Thesis
      Nowadays, information technology has been deeply integrated in our daily life. However, within its rapid development, it faces a serious bottleneck due to the prohibitive power consumption and limited transmission bandwidth ...
