    • Coherence protection in coupled qubit systems 

      Cammack, Helen Mary (University of St Andrews, 2018-12-06) - Thesis
      Decoherence is a major barrier to the implementation of quantum technologies. Theoretical techniques for understanding decoherence in composite systems have traditionally been focused on systems with distinguishable emission ...
    • The effects of disorder in strongly interacting quantum systems 

      Thomson, Steven (University of St Andrews, 2016-11-30) - Thesis
      This thesis contains four studies of the effects of disorder and randomness on strongly correlated quantum phases of matter. Starting with an itinerant ferromagnet, I first use an order-by-disorder approach to show that ...
    • Electrical transport properties of URhGe and BiPd at very low temperature 

      Barraclough, Jack Matthew (University of St Andrews, 2015-06-24) - Thesis
      URhGe has garnered interest recently as one of the few known ferromagnetic superconductors. The superconductivity in this material appears to arise from magnetic fluctuations rather than phonons, and take a triplet form ...
    • Investigation of correlated electron systems under uni-axial strain 

      Brodsky, Daniel Owen (University of St Andrews, 2015) - Thesis
      A central paradigm for classifying the phases of correlated electron systems is their symmetry. Having the ability to controllably tune symmetry-related properties of the system is therefore a powerful probe. In this ...
    • Non-equilibrium quantum dynamics : interplay of disorder, interactions and confinement 

      Schulz, Maximilian (University of St Andrews, 2019-06-24) - Thesis
      The study of collective behaviour in many-body systems often explores fundamentally new ideas absent from the mere constituents of such a system. A paradigmatic model for these studies is the spin-1/2 XXZ chain and its ...
    • Organic polaritons : modelling the effect of vibrational dressing 

      Ćwik, Justyna Agnieszka (University of St Andrews, 2015-11-30) - Thesis
      This thesis is a theoretical study of the effects of vibrational degrees of freedom on the polariton physics. The work is motivated by recent experiments, which show that by allowing light to strongly couple with organic ...
    • Uniaxial strain and high magnetic field investigation on materials with novel order parameters 

      Zhao, Lishan (University of St Andrews, 2016-06-22) - Thesis
      At low temperatures, strongly correlated materials, which typically contain partially filled d- or f-electron shells, often exhibit phases with interesting properties, which may be of both research value and technological ...
