    Bruno, Carlo Giulio (The University of Edinburgh, 2017-11-30)
    The 17;18O(p,α)14;15N nuclear reactions play an important role in several astrophysical scenarios, and in Asymptotic Giant Branch (AGB) stars in particular. These stars are the site of several mixing and recirculating ...
  • Using numerical simulations to identify observational signatures of self-gravitating protostellar discs 

    Hall, Cassandra (The University of Edinburgh, 2017-11-30)
    In this thesis, I study numerical and semi-analytical models of self-gravitating protostellar discs, with the aim of furthering our understanding of the role of disc-self gravity in planet formation. At the time of ...
  • Physics of the flow of concentrated suspensions 

    Guy, Ben Michael (The University of Edinburgh, 2017-07-10)
    A particulate suspension under shear is a classic example of a system driven out of equilibrium. While it is possible to predict the equilibrium phase behaviour of a quiescent suspension, linking microscopic details to ...
  • Role of phenotype switching during biological evolution in static environments 

    Tadrowski, Andrew Charteris (The University of Edinburgh, 2017-07-10)
    Biological evolution is an inherently non-equilibrium process, by which a population acquires a new genetic composition, optimally suited to its present environment. Far from being the slow process it is traditionally ...
  • Evolution of galaxies and black holes, and the origin of cosmic reionization 

    Parsa, Shaghayegh (The University of Edinburgh, 2018-07-02)
    In recent years, advances in deep optical, and especially deep near-infrared imaging with the Hubble Space Telescope (HST) and wide-field ground-based telescopes such as VISTA, have revolutionized our understanding of ...
  • Subleading corrections to hadronic cross-sections at high energies 

    Cockburn, James David (The University of Edinburgh, 2017-11-30)
    The Large Hadron Collider (LHC) has provided, and will continue to provide, data for collisions at the highest energies ever seen in a particle accelerator. A strong knowledge of the properties of amplitudes for Quantum ...
  • Purely elastic shear flow instabilities: linear stability, coherent states and direct numerical simulations 

    Searle, Toby William (The University of Edinburgh, 2017-07-10)
    Recently, a new kind of turbulence has been discovered in the flow of concentrated polymer melts and solutions. These flows, known as purely elastic flows, become unstable when the elastic forces are stronger than the ...
  • Nonequilibrium emergent interactions between run-and-tumble random walkers 

    Slowman, Alexander Barrett (The University of Edinburgh, 2018-07-02)
    Nonequilibrium statistical physics involves the study of many-particle systems that break time reversibility|also known as detailed balance|at some scale. For states in thermal equilibrium, which must respect detailed ...
  • Minimal models of invasion and clonal selection in cancer 

    Paterson, Chay Giles Blair (The University of Edinburgh, 2018-07-02)
    One of the defining features of cancer is cell migration: the tendency of malignant cells to become motile and move significant distances through intervening tissue. This is a necessary precondition for metastasis, the ...
  • Carbon burning in stars: an experimental study of the 12C(12C, p)23Na reaction towards astrophysical energies 

    Morales Gallegos, Elia Lizeth (The University of Edinburgh, 2018-07-02)
    Fusion reactions between 12C nuclei are among the most important in stellar evolution since they determine the destiny of massive stars (> 8 M). At thermonuclear energies (Ecm=1.5 ± 0.3 MeV), the 12C+12C reactions mainly ...
  • Probing of dark energy properties in the Universe using astrophysical observations 

    Smer Barreto, Vanessa Stephanie Emilia (The University of Edinburgh, 2017-11-30)
    The astrophysical data of the last two decades have allowed cosmologists to conclude that the present Universe is accelerating. The research carried out to find the origin of this phenomenon has led to the creation of a ...
  • High-pressure high-temperature behaviour of the lanthanide metals 

    Munro, Keith Alistair (The University of Edinburgh, 2017-11-30)
    The high-pressure behaviour of the lanthanide series of metals has been the subject of study since the work of Percy Bridgman in the 1940s. Differences in said behaviour between the different lanthanide metals are ...
  • Measurements of charmless B⁰s meson decays at LHCb 

    Morris, Adam Benjamin (The University of Edinburgh, 2017-11-30)
    Using 3 fbˉ1 of proton-proton collisions, collected at centre-of-mass energies of √s = 7 and 8 TeV by the LHCb detector, several measurements of charmless B⁰s meson decays are made. A search is also performed for a highly ...
  • Neutron reflectivity studies of bacterial membranes, peptides and proteins 

    McKinley, Laura Ellen (The University of Edinburgh, 2017-11-30)
    This thesis uses neutron and x-ray reflectivity to measure the interfacial structures of three molecular components associated with bacteria. Firstly, the way in which the membrane targeting sequence of a cell division ...
  • Lattice phenomenology of heavy quarks using dynamical fermions 

    Khamseh, Ava (The University of Edinburgh, 2017-11-30)
    The Standard Model of particle physics is believed to be only the low energy limit of a more fundamental theory. In order to determine its range of validity, a major part of theoretical and experimental efforts in physics ...
  • Energy-momentum tensor from Wilson flow in lattice φ4-theory 

    Ehret, Susanne (The University of Edinburgh, 2017-11-30)
    The energy-momentum tensor (EMT) is the Noether current associated with translations. It is of interest because, first of all, it has physical meaning as it contains the energy density and the momentum density. Moreover, ...
  • Electronically coarse grained molecular model of water 

    Cipcigan, Flaviu Serban (The University of Edinburgh, 2017-07-10)
    Electronic coarse graining is a technique improving the predictive power of molecular dynamics simulations by representing electrons via a quantum harmonic oscillator. This construction, known as a Quantum Drude Oscillator, ...
  • Aspects of trace anomaly in perturbation theory and beyond 

    Prochazka, Vladimir (The University of Edinburgh, 2017-07-10)
    In this thesis we study the connection between conformal symmetry breaking and the the renormalization group. In the first chapter we review the main properties of conformal field theories (CFTs), Wilsonian RG and describe ...

    Mogull, David Gustav (The University of Edinburgh, 2017-11-30)
    Pure Yang-Mills amplitudes with all external gluons carrying positive helicity, known as all-plus amplitudes, have an especially simple structure. The tree amplitudes vanish and, up to at least two loops, the loop-level ...

    Waelkens, Andries Jozef Nicolaas (The University of Edinburgh, 2017-11-30)
    When calculating scattering processes in theories involving massless gauge bosons, such as gluons in Quantum Chromodynamics (QCD), one encounters infrared (IR), or soft, divergences. To obtain precise predictions, it is ...
