  • Theory and Lattice Boltzmann simulation of active fluids 

    De Magistris, Giulio (The University of Edinburgh, 2019-11-26)
    Active fluids are far from equilibrium systems, nominally highly dense suspensions of elongated elements that confer to the liquid orientational order, similar in nature to the one found in liquid crystals, and an internal ...
  • Reconstructing Horndeski theories from cosmological observables 

    Kennedy, Joseph (The University of Edinburgh, 2019-11-26)
    The nature of the accelerated expansion of the Universe remains one of the greatest challenges in modern physics. The simplest explanation is that the acceleration is driven by a cosmological constant. Large quantum ...
  • Women's representation and experiences in the high performance computing community 

    Frantzana, Athina (The University of Edinburgh, 2019-11-26)
    Gender imbalance in STEM disciplines (Science, Technology, Engineering and Mathematics) has been a research subject for years. Studies have shown potential reasons leading to the underrepresentation of women in such ...
  • Consequences of dissipative dynamics in the early universe 

    Hernández Jiménez., Rafael (The University of Edinburgh, 2019-11-26)
    Warm inflation presents an exceptional description of the early universe cosmology. It is a scenario of an inflationary dynamics in which the state of the universe during inflation is not the vacuum state, but rather an ...
  • Cosmology with underdensities of the cosmic web 

    Demchenko, Vasiliy Grigoriyvich (The University of Edinburgh, 2019-08-19)
    This thesis explores the utilisation of underdense regions of the Cosmic Web as a tool for studying cosmology. Underdensities, known as cosmic voids, provide a complementary approach for understanding the large-scale ...
  • Two-reggeon exchange to all loop orders 

    Reichel, Joscha (The University of Edinburgh, 2019-11-26)
    In the limit of very large centre-of-mass energy s the two-parton scattering amplitude is well approximated by the exchange of reggeons in the t channel. In particular, the leading contributions to the signature-even ...
  • Effect of roughness on emulsification physics and phase inversion 

    Sawiak, Laura Jane (The University of Edinburgh, 2019-11-26)
    Emulsions, a kinetically stable dispersion of droplets within a second, immiscible fluid, are industrially important. Phase inversion is the process by which the dispersed phase becomes continuous and vice versa. This ...
  • Brown dwarfs and giant exoplanets: bridging observations and theory with statistical methods 

    Fontanive, Clémence Cécile Pia (The University of Edinburgh, 2019-11-26)
    Stellar physics has been widely studied over the last century, with theoretical models for stars robustly tested by decades of observations. In contrast, studies of brown dwarfs and extra-solar giant planets were only ...
  • Probing large-order perturbative expansions in lattice gauge theories with fermions 

    Filaci, Gianluca (The University of Edinburgh, 2019-11-26)
    Many perturbative expansions in quantum field theories are believed to be plagued by factorial divergences. This can be seen as a reflection of the fact that an all-order perturbative computation cannot give a complete ...
  • Spectral properties of homogeneous magnetohydrodynamic turbulence 

    McKay, Màiri Elise (The University of Edinburgh, 2019-11-26)
    Magnetohydrodynamics (MHD) is the study of how an electrically-conducting fluid interacts with a magnetic field. Many of the constituents of the universe possess a magnetic field and MHD has applications ranging from ...
  • Effects of mechanical forces on the shape of confined E. Coli micro-colonies in Agarose 

    Williams, Joshua Jon (The University of Edinburgh, 2019-11-26)
    Bacterial colonies and biofilms play an important role in many aspects of human life. Communities formed by harmful bacteria are responsible for human and animal infections and food spoilage, but beneficial bacteria find ...
  • Novel droplet ripening behaviour in ternary oil-alcohol-water systems 

    Otero Márquez, Javier (The University of Edinburgh, 2019-07-01)
    An ever increasing interest in reducing costs and the energy impact of different manufacturing processes is one of the main drives in industrial fields such as the food and pharmaceutical sectors. In these fields, often ...
  • New results for two-loop scattering in quantum chromodynamics 

    Brønnum-Hansen, Christian (The University of Edinburgh, 2019-07-01)
    Decreasing statistical and systematic uncertainties for particle collisions experiments at the Large Hadron Collider (LHC) put increasing demands on precision in theoretical predictions. At the LHC protons are collided at ...
  • Optical and X-ray properties of galaxy clusters 

    Manolopoulou, Maria (The University of Edinburgh, 2019-07-01)
    Galaxy clusters are very useful astronomical tools; they are used as a means to study galaxy formation and evolution, large scale structure, but also as probes to constrain cosmological parameters. This work aims to ...
  • New scintillation hodoscope for CLAS12 and partial wave analysis of the channel γ p → p K⁺ K⁻ 

    Stankovic, Ivana (The University of Edinburgh, 2019-07-01)
    This thesis consists of two parts that have contributed to a new meson spectroscopy program, MesonEx, which is currently taking place in Hall B of the upgraded Thomas Jefferson National Accelerator Facility (JLab) in the ...
  • Structural basis for the rheology of molten chocolate: a multi-technique approach 

    Manasi, Iva (The University of Edinburgh, 2019-07-01)
    Chocolate comprises a dense suspension of solids, mainly sucrose with cocoa and milk solids, in a continuous fat phase of cocoa butter stabilised by surfactants, namely lecithin (mostly phospholipid), and sometimes ...
  • Mixtures of proteins and protein-stabilised droplets: rheology of emulsions and emulsion gels 

    Roullet, Marion Sarah (The University of Edinburgh, 2019-07-01)
    The soft materials formed from emulsions stabilised by proteins, like yogurt, are referred to as emulsion gels. This designation is however not precise enough to reflect the variety of composition of these materials. ...
  • Chromosome folding and organisation across different organisms: a molecular dynamics study 

    Pereira, Maria Carolina (The University of Edinburgh, 2019-07-01)
    Polymer models have long been used to study the properties and behaviour of DNA, however the principles behind chromosome folding and organisation remain elusive. In this thesis we will analyse the contributions of different ...
  • Spatially resolved physical properties of high-redshift galaxies observed with KMOS 

    Turner, Owen James (The University of Edinburgh, 2019-07-01)
    The formation and evolution of galaxies is governed by a set of complex non-linear physical processes. When we observe a galaxy at a particular epoch, we see a unique spatial distribution of stars, gas and dust, and can ...
  • β-decay studies of r-process nuclei using the Advanced Implantation Detector Array (AIDA) 

    Griffin, Christopher James (The University of Edinburgh, 2019-07-01)
    The origin of the heavy elements is one of the most fundamental open questions in modern astrophysics, with a notable difficulty being the lack of a complete description of the rapid neutron-capture process (r-process), ...
