Low dimensional models of the transition to turbulence
(The University of Edinburgh, 2021-07-31)The transition from a regularly ordered state of fluid motion to chaotic and turbulent regime has been long observed and progressively understood through the discovery and application of theoretical tools and frameworks. ... -
Formation, structure and mechanical properties of hydrogel-emulsions
(The University of Edinburgh, 2021-07-31)Oil-in-water emulsions are ubiquitous in fields such as food, cosmetic and pharmaceutical industries due to their ability to impart texture, or transport or solubilise hydrophobic constituents in a water continuous phase. ... -
Phase transformation and transport in sulphur at high pressure and temperature.
(The University of Edinburgh, 2021-07-31)Sulphur has one of the most complex high pressure-temperature phase diagrams of the elements, with many solid phases and multiple liquid phases reported up to 40 GPa (400 kbar). The high temperature stability of solid ... -
Investigation of the bacterial mechanosensitive ion channel of large conductance within bacterial membrane mimetics in response to simple antimicrobial molecules
(The University of Edinburgh, 2021-07-31)This thesis describes the use of neutron and X-ray scattering and reflectivity to characterize the structure of the Mechanosensitive Ion Channel of Large Conductance, MscL, within bilayer constructs. MscL is known to ... -
B meson decays, conformal anomalies and gauge invariance
(The University of Edinburgh, 2021-07-31)In this thesis, we discuss the calculation of conformal anomalies using curved spacetime and heat-kernel techniques, and QED corrections to semi-leptonic decays of the pseudoscalar B meson at the full differential level. ... -
Computer simulations of biofilm spatial structure
(The University of Edinburgh, 2020-11-30)Surface attached communities of bacteria, known as biofilms, can grow in a variety of morphological forms. Classifying these distinct spatial structures is important for understanding the link between the spatial structure ... -

(The University of Edinburgh, 2020-11-30)Neutrino oscillation is a well-established phenomenon and oscillation parameters are being measured with great accuracy. This unprecedented accuracy allows sensitivity to sub dominant effects which could indicate new ... -
Neutron scattering studies of hydrogenated molecular materials
(The University of Edinburgh, 2021-07-31)This thesis employs three neutron scattering techniques; neutron diffraction, inelastic neutron scattering, and quasielastic neutron scattering; to probe the properties of hydrogenous systems. These results are complemented ... -
Modelling cosmological structure formation in the non-linear regime

(The University of Edinburgh, 2020-11-30)The LHCb experiment at the Large Hadron Collider (LHC) at CERN is designed to search for indirect evidence of physics beyond the Standard Model (SM) in CP violation and rare decays of beauty and charm hadrons. One of the ... -
Sensitivity projections for hidden photons and axion-like particles in the LUX-ZEPLIN experiment
(The University of Edinburgh, 2020-11-30)The particle nature of dark matter is one of the yet unresolved puzzles in contemporary physics. The properties of dark matter, as revealed by several types of cosmological evidence, are inconsistent with the Standard Model ... -
Infrared divergences in scattering amplitudes from correlators of Wilson Lines
(The University of Edinburgh, 2020-11-30)Scattering amplitudes in theories with massless particles feature infrared (IR) divergences. In QCD, gluons are massless and when their momenta tends to zero the amplitude diverges. We call this a soft divergence. For ...
