    • The physics of microchip lasers : spatial and spectral selectivity mechanisms 

      Kemp, Alan (University of St Andrews, 2000) - Thesis
      This thesis describes an experimental and theoretical exploration of some of the physics of microchip lasers and micro-lasers, with particular reference to the selection of the transverse and longitudinal modes. The guiding ...

    • Nuclear magnetic resonance in isopentane at low temperatures 

      Forsyth, Alan G. (University of St Andrews, 1964) - Thesis
      Nuclear Magnetic Resonance depends for its existence on the fact that most nuclei of the elements exhibit gyromagnetic properties. These properties were first attributed to the nucleus by Pauli (1921) to explain hyperfine ...

    • Neutron scattering and muon-spin rotation studies of superconducting materials 

      Drew, Alan J. (University of St Andrews, 2005) - Thesis
      Small angle neutron scattering (SANS), muon spin rotation (μSR) and associated characterisation techniques have been used to measure novel properties of supercon¬ ducting materials. The coexistence of Type-I and Type-II ...

    • A μSR study of unconventional superconductors 

      Hillier, Adrian (University of St Andrews, 1999) - Thesis
      The problem of finding an appropriate classification scheme for the remarkably diverse range of known superconducting materials is a long standing one. Nevertheless the literature abounds with claims of discoveries of "new ...

    • Dynamical backaction effects between localised spins and electronic conductors 

      Matern, Stephanie (University of St Andrews, 2020-12-01) - Thesis
      In this thesis we present an investigation of the influence of quantum correlations on a quantum system’s dynamical behaviour. Our focus is specifically on the time dependence of quantum spins in an environment of itinerant ...
