  • Canonical quantization of macroscopic electromagnetism 

    Philbin, Thomas Gerard (2010-12) - Journal article
    Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption. This has led to a phenomenological ...
  • Exotic order in magnetic systems from Majorana fermions 

    Bennett, Edmund (University of St Andrews, 2016-11-30) - Thesis
    This thesis explores the theoretical representation of localised electrons in magnetic systems, using Majorana fermions. A motivation is provided for the Majorana fermion representation, which is then developed and applied ...
  • Negative frequency at the horizon : scattering of light at a refractive index front 

    Jacquet, Maxime J. (University of St Andrews, 2017-12-07) - Thesis
    This thesis considers the problem of calculating and observing the mixing of modes of positive and negative frequency in inhomogeneous, dispersive media. Scattering of vacuum modes of the electromagnetic field at a moving ...
  • Spin dynamics of quantum spin-ladders and chains 

    Notbohm, Susanne (University of St Andrews, 2007-11-23) - Thesis
    This thesis describes the neutron scattering measurements of magnetic excitations in spin-chains and ladders. The first part discusses an experimental investigation of the copper oxide family Srâ â Cuâ â Oâ â ...
  • Surprises in theoretical Casimir physics : quantum forces in inhomogeneous media 

    Simpson, William M. R. (University of St Andrews, 2014-06-25) - Thesis
    This thesis considers the problem of determining Casimir-Lifshitz forces in inhomogeneous media. The ground-state energy of the electromagnetic field in a piston-geometry is discussed. When the cavity is empty, the ...
