    • 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 ...
    • Quantization of some generally covariant model field theories 

      Wan, Kong K. (University of St Andrews, 1971) - Thesis
      This thesis reports a study of the quantization of generally covariant and nonlinear field theories. It begins by reviewing some existing general theories in Chapter 2 and Chapter 3, Chapter 2 deals with general classical ...
    • 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 ...
